78115320 ÷ 957 
We're looking to find how many times 957 goes into 78115320.

Step 1:
When dividing 7 by 957, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 957

Going ahead to step 2:
78 divided by 957 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 957

Going ahead to step 3:
When dividing 781 by 957, we get 0 with a remainder of 781.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 781, we get 781.
Fetch the next digit (1) from the dividend, attach it to 781 and continue: 7811 / 957

Moving on to step 4:
957 can be fit into 7811 8 times, resulting in a remainder of 155.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 7656 from 7811 and we're left with 155.
Take the next digit (5) from the dividend and append it to 155, then repeat: 1555 / 957

On to step 5:
957 goes into 1555 1 times with a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 598 after subtracting 957 from 1555.
Include the next digit (3) from the dividend after 598, then repeat: 5983 / 957

Step 6:
957 goes into 5983 6 times with a remainder of 241.
The next digit of our result is 6. 
Result so far: 816.0
Deduct 5742 from 5983 and we're left with 241.
Take the next digit (2) from the dividend and append it to 241, then repeat: 2412 / 957

Step 7:
When dividing 2412 by 957, we get 2 with a remainder of 498.
The number 2 becomes the next digit in our result. 
Result so far: 8162.0
Deduct 1914 from 2412 and we're left with 498.
Include the next digit (0) from the dividend after 498, then repeat: 4980 / 957

Let's proceed to step 8:
The number 957 fits into 4980 5 times, leaving a remainder of 195.
The next digit of our result is 5. 
Result so far: 81625.0
If we subtract 4785 from 4980, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 9:
If we divide 1950 by 957, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 81625.2
If we subtract 1914 from 1950, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
When dividing 360 by 957, we get 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 81625.2
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
If we divide 3600 by 957, we get 3 and a remainder of 729.
Record the quotient 3 as the next digit in the result. 
Result so far: 81625.203
If we subtract 2871 from 3600, we get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Moving on to step 12:
If we divide 7290 by 957, we get 7 and a remainder of 591.
Use 7 as the next digit of our solution. 
Result so far: 81625.2037
If we subtract 6699 from 7290, 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 13:
957 goes into 5910 6 times with a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 81625.20376
Deduct 5742 from 5910 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
1680 divided by 957 is 1 with a remainder of 723.
The number 1 becomes the next digit in our result. 
Result so far: 81625.203761
If we subtract 957 from 1680, we get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 15:
When dividing 7230 by 957, we get 7 with a remainder of 531.
Put 7 as the next digit of the answer. 
Result so far: 81625.2037617
The remainder is 531 after subtracting 6699 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 16:
If we divide 5310 by 957, we get 5 and a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 81625.20376175
The remainder is 525 after subtracting 4785 from 5310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The final outcome is 81625.20376175, with a leftover of 5.25e-07.
