We're dividing 79171352 by 397 
We want to figure out the number of times 79171352 can be divided by 397.

Going ahead to step 1:
The number 397 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 397

Going ahead to step 2:
If we divide 79 by 397, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 397

On to step 3:
791 divided by 397 is 1 with a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 394 after subtracting 397 from 791.
Bring next digit (7) of the dividend behind the 394 and repeat the process: 3947 / 397

Let's proceed to step 4:
If we divide 3947 by 397, we get 9 and a remainder of 374.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 3573 away from 3947, we end up with 374.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 397

Step 5:
The number 397 fits into 3741 9 times, leaving a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Subtract 3573 from 3741 to get 168.
Bring next digit (3) of the dividend behind the 168 and repeat the process: 1683 / 397

Step 6:
The number 397 fits into 1683 4 times, leaving a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 1994.0
Deduct 1588 from 1683 and we're left with 95.
Fetch the next digit (5) from the dividend, attach it to 95 and continue: 955 / 397

Moving on to step 7:
If we divide 955 by 397, we get 2 and a remainder of 161.
Put 2 as the next digit of the answer. 
Result so far: 19942.0
Deduct 794 from 955 and we're left with 161.
Include the next digit (2) from the dividend after 161, then repeat: 1612 / 397

Let's proceed to step 8:
397 goes into 1612 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 199424.0
Subtract 1588 from 1612 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 397, we get 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 199424.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
397 can be fit into 2400 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 199424.06
If we take 2382 away from 2400, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
397 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 199424.06
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
1800 divided by 397 is 4 with a remainder of 212.
The next digit of our result is 4. 
Result so far: 199424.0604
Subtract 1588 from 1800 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 13:
2120 divided by 397 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 199424.06045
If we subtract 1985 from 2120, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 14:
397 goes into 1350 3 times with a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 199424.060453
If we subtract 1191 from 1350, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 15:
397 can be fit into 1590 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 199424.0604534
Subtracting 1588 from 1590 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 16:
397 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 199424.0604534
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 199424.0604534 with a balance of 2e-08.
