Let's divide 54693309 by 397
We want to divide 54693309 by 397.

Let's proceed to step 1:
When dividing 5 by 397, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 397

On to step 2:
If we divide 54 by 397, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 397

Moving on to step 3:
When dividing 546 by 397, we get 1 with a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 397 from 546 to get 149.
Include the next digit (9) from the dividend after 149, then repeat: 1499 / 397

Advancing to step 4:
If we divide 1499 by 397, we get 3 and a remainder of 308.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1191 from 1499 leaves us with 308.
Grab the next digit (3) from the dividend, add it to 308, then carry on: 3083 / 397

Step 5:
397 goes into 3083 7 times with a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 2779 from 3083 and we're left with 304.
Fetch the next digit (3) from the dividend, attach it to 304 and continue: 3043 / 397

Advancing to step 6:
397 goes into 3043 7 times with a remainder of 264.
The next digit of our result is 7. 
Result so far: 1377.0
The remainder is 264 after subtracting 2779 from 3043.
Include the next digit (0) from the dividend after 264, then repeat: 2640 / 397

Step 7:
397 goes into 2640 6 times with a remainder of 258.
The next digit of our result is 6. 
Result so far: 13776.0
If we take 2382 away from 2640, we end up with 258.
Include the next digit (9) from the dividend after 258, then repeat: 2589 / 397

Advancing to step 8:
If we divide 2589 by 397, we get 6 and a remainder of 207.
Put 6 as the next digit of the answer. 
Result so far: 137766.0
If we take 2382 away from 2589, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 9:
397 goes into 2070 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 137766.5
If we take 1985 away from 2070, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
When dividing 850 by 397, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 137766.52
Subtracting 794 from 850 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
560 divided by 397 is 1 with a remainder of 163.
The next digit of our result is 1. 
Result so far: 137766.521
Subtract 397 from 560 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 12:
The number 397 fits into 1630 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 137766.5214
Subtract 1588 from 1630 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
The number 397 fits into 420 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 137766.52141
The remainder is 23 after subtracting 397 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
If we divide 230 by 397, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 137766.52141
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
The number 397 fits into 2300 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 137766.5214105
If we take 1985 away from 2300, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 16:
397 goes into 3150 7 times with a remainder of 371.
Write down 7 as next digit of the result. 
Result so far: 137766.52141057
If we subtract 2779 from 3150, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final result is 137766.52141057 with a remainder of 3.71e-07.
