Let's divide 78766839 by 117
We're looking to find how many times 117 goes into 78766839.

Advancing to step 1:
The number 117 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 117

Going ahead to step 2:
The number 117 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 117

On to step 3:
117 can be fit into 787 6 times, resulting in a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 85 after subtracting 702 from 787.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 117

Moving on to step 4:
117 can be fit into 856 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 37 after subtracting 819 from 856.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 117

Moving on to step 5:
If we divide 376 by 117, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
If we take 351 away from 376, we end up with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 117

Step 6:
117 can be fit into 258 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6732.0
Subtracting 234 from 258 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 117

Moving on to step 7:
117 can be fit into 243 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 67322.0
Subtract 234 from 243 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 117

Going ahead to step 8:
99 divided by 117 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 673220.0
Deduct 0 from 99 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
The number 117 fits into 990 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 673220.8
The remainder is 54 after subtracting 936 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
117 can be fit into 540 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 673220.84
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
117 can be fit into 720 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 673220.846
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
117 can be fit into 180 1 times, resulting in a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 673220.8461
The remainder is 63 after subtracting 117 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 13:
630 divided by 117 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 673220.84615
Subtracting 585 from 630 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
117 goes into 450 3 times with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 673220.846153
If we subtract 351 from 450, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 15:
117 can be fit into 990 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 673220.8461538
If we take 936 away from 990, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
The number 117 fits into 540 4 times, leaving a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 673220.84615384
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 673220.84615384, and the remainder is 7.2e-08.
