76858129 ÷ 117 
Our goal is to divide 76858129 by 117.

Let's proceed to step 1:
117 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 117

Moving on to step 2:
If we divide 76 by 117, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 117

On to step 3:
117 goes into 768 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 66 after subtracting 702 from 768.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 117

Going ahead to step 4:
When dividing 665 by 117, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
If we take 585 away from 665, we end up with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 117

Moving on to step 5:
117 goes into 808 6 times with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
If we subtract 702 from 808, we get 106.
Include the next digit (1) from the dividend after 106, then repeat: 1061 / 117

Moving on to step 6:
117 can be fit into 1061 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 6569.0
If we subtract 1053 from 1061, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 117

Step 7:
82 divided by 117 is 0 with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 65690.0
Deduct 0 from 82 and we're left with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 117

On to step 8:
If we divide 829 by 117, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 656907.0
If we subtract 819 from 829, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 117, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 656907.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
If we divide 1000 by 117, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 656907.08
If we take 936 away from 1000, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
117 goes into 640 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 656907.085
The remainder is 55 after subtracting 585 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
117 can be fit into 550 4 times, resulting in a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 656907.0854
Subtracting 468 from 550 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
820 divided by 117 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 656907.08547
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
If we divide 10 by 117, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 656907.08547
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
100 divided by 117 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 656907.08547
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 656907.08547 and a remainder of 1e-06.
