78666916 divided by 958 
Let's see how many times 958 fits into 78666916.

Advancing to step 1:
When dividing 7 by 958, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 958

Moving on to step 2:
958 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 958

Moving on to step 3:
When dividing 786 by 958, we get 0 with a remainder of 786.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 786, we get 786.
Grab the next digit (6) from the dividend, add it to 786, then carry on: 7866 / 958

Going ahead to step 4:
958 can be fit into 7866 8 times, resulting in a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7664 from 7866, we get 202.
Append the next digit (6) from the dividend to 202 and continue with: 2026 / 958

Let's proceed to step 5:
If we divide 2026 by 958, we get 2 and a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 82.0
The remainder is 110 after subtracting 1916 from 2026.
Append the next digit (9) from the dividend to 110 and continue with: 1109 / 958

Moving on to step 6:
1109 divided by 958 is 1 with a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 821.0
Deduct 958 from 1109 and we're left with 151.
Take the next digit (1) from the dividend and append it to 151, then repeat: 1511 / 958

Moving on to step 7:
If we divide 1511 by 958, we get 1 and a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 8211.0
Subtracting 958 from 1511 leaves us with 553.
Bring next digit (6) of the dividend behind the 553 and repeat the process: 5536 / 958

Going ahead to step 8:
If we divide 5536 by 958, we get 5 and a remainder of 746.
Write down 5 as next digit of the result. 
Result so far: 82115.0
Deduct 4790 from 5536 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 9:
958 goes into 7460 7 times with a remainder of 754.
The next digit of our result is 7. 
Result so far: 82115.7
The remainder is 754 after subtracting 6706 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Moving on to step 10:
7540 divided by 958 is 7 with a remainder of 834.
The number 7 becomes the next digit in our result. 
Result so far: 82115.77
The remainder is 834 after subtracting 6706 from 7540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

The final outcome is 82115.77, with a leftover of 0.834.
