We look at the division of 15996811 by 397 
We want to figure out the number of times 15996811 can be divided by 397.

Moving on to step 1:
1 divided by 397 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 397

Let's proceed to step 2:
397 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 397

Advancing to step 3:
When dividing 159 by 397, we get 0 with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 159, we end up with 159.
Bring next digit (9) of the dividend behind the 159 and repeat the process: 1599 / 397

Let's proceed to step 4:
The number 397 fits into 1599 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1588 from 1599 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 397

Moving on to step 5:
397 goes into 116 0 times with a remainder of 116.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 116, we end up with 116.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 397

Moving on to step 6:
The number 397 fits into 1168 2 times, leaving a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
The remainder is 374 after subtracting 794 from 1168.
Grab the next digit (1) from the dividend, add it to 374, then carry on: 3741 / 397

Step 7:
If we divide 3741 by 397, we get 9 and a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 4029.0
The remainder is 168 after subtracting 3573 from 3741.
Append the next digit (1) from the dividend to 168 and continue with: 1681 / 397

Moving on to step 8:
397 goes into 1681 4 times with a remainder of 93.
Use 4 as the next digit of our solution. 
Result so far: 40294.0
If we take 1588 away from 1681, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
397 can be fit into 930 2 times, resulting in a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 40294.2
Deduct 794 from 930 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
When dividing 1360 by 397, we get 3 with a remainder of 169.
The number 3 becomes the next digit in our result. 
Result so far: 40294.23
Subtracting 1191 from 1360 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 11:
397 goes into 1690 4 times with a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 40294.234
If we subtract 1588 from 1690, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
1020 divided by 397 is 2 with a remainder of 226.
Put 2 as the next digit of the answer. 
Result so far: 40294.2342
If we take 794 away from 1020, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 13:
397 goes into 2260 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 40294.23425
The remainder is 275 after subtracting 1985 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 14:
The number 397 fits into 2750 6 times, leaving a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 40294.234256
If we subtract 2382 from 2750, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 15:
When dividing 3680 by 397, we get 9 with a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 40294.2342569
If we take 3573 away from 3680, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 16:
397 can be fit into 1070 2 times, resulting in a remainder of 276.
The next digit of our result is 2. 
Result so far: 40294.23425692
If we subtract 794 from 1070, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 40294.23425692, and the remainder is 2.76e-07.
