79010958 ÷ 668 
Our goal is to divide 79010958 by 668.

Advancing to step 1:
When dividing 7 by 668, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 668

Advancing to step 2:
668 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 668

Moving on to step 3:
668 goes into 790 1 times with a remainder of 122.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 668 from 790 and we're left with 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 668

Advancing to step 4:
1221 divided by 668 is 1 with a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 668 away from 1221, we end up with 553.
Include the next digit (0) from the dividend after 553, then repeat: 5530 / 668

On to step 5:
668 goes into 5530 8 times with a remainder of 186.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtracting 5344 from 5530 leaves us with 186.
Append the next digit (9) from the dividend to 186 and continue with: 1869 / 668

Let's proceed to step 6:
668 goes into 1869 2 times with a remainder of 533.
The next digit of our result is 2. 
Result so far: 1182.0
The remainder is 533 after subtracting 1336 from 1869.
Bring next digit (5) of the dividend behind the 533 and repeat the process: 5335 / 668

Let's proceed to step 7:
When dividing 5335 by 668, we get 7 with a remainder of 659.
Write down 7 as next digit of the result. 
Result so far: 11827.0
If we take 4676 away from 5335, we end up with 659.
Take the next digit (8) from the dividend and append it to 659, then repeat: 6598 / 668

On to step 8:
The number 668 fits into 6598 9 times, leaving a remainder of 586.
Write down 9 as next digit of the result. 
Result so far: 118279.0
Deduct 6012 from 6598 and we're left with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 9:
668 can be fit into 5860 8 times, resulting in a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 118279.8
Subtract 5344 from 5860 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 10:
The number 668 fits into 5160 7 times, leaving a remainder of 484.
Put 7 as the next digit of the answer. 
Result so far: 118279.87
If we subtract 4676 from 5160, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 11:
4840 divided by 668 is 7 with a remainder of 164.
The number 7 becomes the next digit in our result. 
Result so far: 118279.877
Subtracting 4676 from 4840 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 118279.877, with a leftover of 0.0164.
