We look at the division of 79728491 by 398 
We want to divide 79728491 by 398.

On to step 1:
The number 398 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 take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 398

Step 2:
If we divide 79 by 398, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 398

Going ahead to step 3:
398 goes into 797 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 796 away from 797, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 398

Moving on to step 4:
If we divide 12 by 398, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 398

Let's proceed to step 5:
398 goes into 128 0 times with a remainder of 128.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 128, we end up with 128.
Append the next digit (4) from the dividend to 128 and continue with: 1284 / 398

Advancing to step 6:
When dividing 1284 by 398, we get 3 with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 2003.0
Deduct 1194 from 1284 and we're left with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 398

On to step 7:
The number 398 fits into 909 2 times, leaving a remainder of 113.
Put 2 as the next digit of the answer. 
Result so far: 20032.0
Subtract 796 from 909 to get 113.
Append the next digit (1) from the dividend to 113 and continue with: 1131 / 398

Let's proceed to step 8:
When dividing 1131 by 398, we get 2 with a remainder of 335.
The next digit of our result is 2. 
Result so far: 200322.0
Deduct 796 from 1131 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
The number 398 fits into 3350 8 times, leaving a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 200322.8
Subtract 3184 from 3350 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 10:
398 can be fit into 1660 4 times, resulting in a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 200322.84
Deduct 1592 from 1660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
When dividing 680 by 398, we get 1 with a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 200322.841
Deduct 398 from 680 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
398 goes into 2820 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 200322.8417
Subtracting 2786 from 2820 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
When dividing 340 by 398, we get 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 200322.8417
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
398 can be fit into 3400 8 times, resulting in a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 200322.841708
Deduct 3184 from 3400 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
If we divide 2160 by 398, we get 5 and a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 200322.8417085
Deduct 1990 from 2160 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 16:
398 goes into 1700 4 times with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 200322.84170854
Subtract 1592 from 1700 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 200322.84170854, with a leftover of 1.08e-07.
