We look at the division of 79539981 by 668 
We want to divide 79539981 by 668.

Advancing to step 1:
If we divide 7 by 668, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 668

Moving on to step 2:
If we divide 79 by 668, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 668

Advancing to step 3:
668 can be fit into 795 1 times, resulting in a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 668 from 795 and we're left with 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 668

On to step 4:
1273 divided by 668 is 1 with a remainder of 605.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 668 from 1273 and we're left with 605.
Grab the next digit (9) from the dividend, add it to 605, then carry on: 6059 / 668

On to step 5:
If we divide 6059 by 668, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 119.0
Subtract 6012 from 6059 to get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 668

Moving on to step 6:
If we divide 479 by 668, we get 0 and a remainder of 479.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
If we subtract 0 from 479, we get 479.
Fetch the next digit (8) from the dividend, attach it to 479 and continue: 4798 / 668

Advancing to step 7:
4798 divided by 668 is 7 with a remainder of 122.
Put 7 as the next digit of the answer. 
Result so far: 11907.0
Subtracting 4676 from 4798 leaves us with 122.
Grab the next digit (1) from the dividend, add it to 122, then carry on: 1221 / 668

Moving on to step 8:
668 goes into 1221 1 times with a remainder of 553.
The number 1 becomes the next digit in our result. 
Result so far: 119071.0
Subtract 668 from 1221 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 9:
The number 668 fits into 5530 8 times, leaving a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 119071.8
If we subtract 5344 from 5530, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
1860 divided by 668 is 2 with a remainder of 524.
The number 2 becomes the next digit in our result. 
Result so far: 119071.82
The remainder is 524 after subtracting 1336 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 11:
668 goes into 5240 7 times with a remainder of 564.
Record the quotient 7 as the next digit in the result. 
Result so far: 119071.827
If we take 4676 away from 5240, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 12:
If we divide 5640 by 668, we get 8 and a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 119071.8278
Deduct 5344 from 5640 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 13:
If we divide 2960 by 668, we get 4 and a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 119071.82784
Subtracting 2672 from 2960 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 14:
When dividing 2880 by 668, we get 4 with a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 119071.827844
If we subtract 2672 from 2880, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 119071.827844 with a remaining 2.08e-05.
