We look at the division of 99458299 by 797 
We want to divide 99458299 by 797.

On to step 1:
If we divide 9 by 797, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 797

Step 2:
99 divided by 797 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 797

On to step 3:
When dividing 994 by 797, we get 1 with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 797 from 994, we get 197.
Fetch the next digit (5) from the dividend, attach it to 197 and continue: 1975 / 797

Going ahead to step 4:
The number 797 fits into 1975 2 times, leaving a remainder of 381.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1594 from 1975 and we're left with 381.
Bring next digit (8) of the dividend behind the 381 and repeat the process: 3818 / 797

Let's proceed to step 5:
When dividing 3818 by 797, we get 4 with a remainder of 630.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtracting 3188 from 3818 leaves us with 630.
Include the next digit (2) from the dividend after 630, then repeat: 6302 / 797

Moving on to step 6:
If we divide 6302 by 797, we get 7 and a remainder of 723.
Use 7 as the next digit of our solution. 
Result so far: 1247.0
Deduct 5579 from 6302 and we're left with 723.
Take the next digit (9) from the dividend and append it to 723, then repeat: 7239 / 797

Moving on to step 7:
7239 divided by 797 is 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 12479.0
If we subtract 7173 from 7239, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 797

On to step 8:
If we divide 669 by 797, we get 0 and a remainder of 669.
The next digit of our result is 0. 
Result so far: 124790.0
The remainder is 669 after subtracting 0 from 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Going ahead to step 9:
797 goes into 6690 8 times with a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 124790.8
Subtract 6376 from 6690 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
797 goes into 3140 3 times with a remainder of 749.
The next digit of our result is 3. 
Result so far: 124790.83
Subtract 2391 from 3140 to get 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Advancing to step 11:
797 goes into 7490 9 times with a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 124790.839
The remainder is 317 after subtracting 7173 from 7490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 12:
797 can be fit into 3170 3 times, resulting in a remainder of 779.
The next digit of our result is 3. 
Result so far: 124790.8393
If we take 2391 away from 3170, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Step 13:
When dividing 7790 by 797, we get 9 with a remainder of 617.
Record the quotient 9 as the next digit in the result. 
Result so far: 124790.83939
If we subtract 7173 from 7790, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 14:
The number 797 fits into 6170 7 times, leaving a remainder of 591.
The next digit of our result is 7. 
Result so far: 124790.839397
If we subtract 5579 from 6170, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 15:
When dividing 5910 by 797, we get 7 with a remainder of 331.
Put 7 as the next digit of the answer. 
Result so far: 124790.8393977
If we subtract 5579 from 5910, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The quotient of the division is 124790.8393977, and the remainder is 3.31e-06.
