76771822 ÷ 870 
Our goal is to divide 76771822 by 870.

Step 1:
If we divide 7 by 870, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 870

Going ahead to step 2:
870 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 870

Step 3:
If we divide 767 by 870, we get 0 and a remainder of 767.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 767, we get 767.
Grab the next digit (7) from the dividend, add it to 767, then carry on: 7677 / 870

On to step 4:
When dividing 7677 by 870, we get 8 with a remainder of 717.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6960 from 7677 and we're left with 717.
Include the next digit (1) from the dividend after 717, then repeat: 7171 / 870

On to step 5:
If we divide 7171 by 870, we get 8 and a remainder of 211.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 211 after subtracting 6960 from 7171.
Include the next digit (8) from the dividend after 211, then repeat: 2118 / 870

Let's proceed to step 6:
If we divide 2118 by 870, we get 2 and a remainder of 378.
The number 2 becomes the next digit in our result. 
Result so far: 882.0
The remainder is 378 after subtracting 1740 from 2118.
Fetch the next digit (2) from the dividend, attach it to 378 and continue: 3782 / 870

Advancing to step 7:
When dividing 3782 by 870, we get 4 with a remainder of 302.
Put 4 as the next digit of the answer. 
Result so far: 8824.0
Subtracting 3480 from 3782 leaves us with 302.
Take the next digit (2) from the dividend and append it to 302, then repeat: 3022 / 870

On to step 8:
When dividing 3022 by 870, we get 3 with a remainder of 412.
Record the quotient 3 as the next digit in the result. 
Result so far: 88243.0
Deduct 2610 from 3022 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 9:
870 can be fit into 4120 4 times, resulting in a remainder of 640.
The next digit of our result is 4. 
Result so far: 88243.4
If we subtract 3480 from 4120, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 10:
870 can be fit into 6400 7 times, resulting in a remainder of 310.
Put 7 as the next digit of the answer. 
Result so far: 88243.47
Subtracting 6090 from 6400 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
3100 divided by 870 is 3 with a remainder of 490.
Write down 3 as next digit of the result. 
Result so far: 88243.473
Subtracting 2610 from 3100 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 12:
870 goes into 4900 5 times with a remainder of 550.
The next digit of our result is 5. 
Result so far: 88243.4735
Deduct 4350 from 4900 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 13:
870 goes into 5500 6 times with a remainder of 280.
The next digit of our result is 6. 
Result so far: 88243.47356
Subtracting 5220 from 5500 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
2800 divided by 870 is 3 with a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 88243.473563
The remainder is 190 after subtracting 2610 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
When dividing 1900 by 870, we get 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 88243.4735632
Deduct 1740 from 1900 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
When dividing 1600 by 870, we get 1 with a remainder of 730.
Write down 1 as next digit of the result. 
Result so far: 88243.47356321
Subtract 870 from 1600 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Our division results in 88243.47356321 with a remaining 7.3e-07.
