We're dividing 71915591 by 398 
We're looking to find how many times 398 goes into 71915591.

Let's proceed to step 1:
The number 398 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 398

Going ahead to step 2:
398 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 398

Going ahead to step 3:
719 divided by 398 is 1 with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 398 from 719 to get 321.
Bring next digit (1) of the dividend behind the 321 and repeat the process: 3211 / 398

Advancing to step 4:
If we divide 3211 by 398, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3184 from 3211 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 398

Advancing to step 5:
398 can be fit into 275 0 times, resulting in a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
If we subtract 0 from 275, we get 275.
Append the next digit (5) from the dividend to 275 and continue with: 2755 / 398

Let's proceed to step 6:
If we divide 2755 by 398, we get 6 and a remainder of 367.
Write down 6 as next digit of the result. 
Result so far: 1806.0
Deduct 2388 from 2755 and we're left with 367.
Fetch the next digit (9) from the dividend, attach it to 367 and continue: 3679 / 398

On to step 7:
3679 divided by 398 is 9 with a remainder of 97.
The number 9 becomes the next digit in our result. 
Result so far: 18069.0
Subtract 3582 from 3679 to get 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 398

Let's proceed to step 8:
398 goes into 971 2 times with a remainder of 175.
The next digit of our result is 2. 
Result so far: 180692.0
Deduct 796 from 971 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
If we divide 1750 by 398, we get 4 and a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 180692.4
The remainder is 158 after subtracting 1592 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
When dividing 1580 by 398, we get 3 with a remainder of 386.
Use 3 as the next digit of our solution. 
Result so far: 180692.43
If we subtract 1194 from 1580, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 11:
398 goes into 3860 9 times with a remainder of 278.
Record the quotient 9 as the next digit in the result. 
Result so far: 180692.439
If we subtract 3582 from 3860, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 12:
2780 divided by 398 is 6 with a remainder of 392.
The number 6 becomes the next digit in our result. 
Result so far: 180692.4396
Subtracting 2388 from 2780 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 13:
398 can be fit into 3920 9 times, resulting in a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 180692.43969
If we subtract 3582 from 3920, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 14:
If we divide 3380 by 398, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 180692.439698
Subtract 3184 from 3380 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 15:
If we divide 1960 by 398, we get 4 and a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 180692.4396984
If we subtract 1592 from 1960, 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.

Going ahead to step 16:
If we divide 3680 by 398, we get 9 and a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 180692.43969849
Subtract 3582 from 3680 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 180692.43969849, with a leftover of 9.8e-08.
