70129412 divided by 87 
We want to divide 70129412 by 87.

Step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 87

Moving on to step 2:
87 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 87

On to step 3:
When dividing 701 by 87, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
If we take 696 away from 701, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 87

Let's proceed to step 4:
87 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 87

Advancing to step 5:
87 goes into 529 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 806.0
If we subtract 522 from 529, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 87

Let's proceed to step 6:
If we divide 74 by 87, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 8060.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 87

Step 7:
If we divide 741 by 87, we get 8 and a remainder of 45.
The next digit of our result is 8. 
Result so far: 80608.0
If we take 696 away from 741, we end up with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 87

Advancing to step 8:
87 can be fit into 452 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 806085.0
Subtract 435 from 452 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 87, we get 1 and a remainder of 83.
The next digit of our result is 1. 
Result so far: 806085.1
If we take 87 away from 170, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 10:
If we divide 830 by 87, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 806085.19
The remainder is 47 after subtracting 783 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
87 can be fit into 470 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 806085.195
Deduct 435 from 470 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
If we divide 350 by 87, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 806085.1954
Deduct 348 from 350 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 87, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 806085.1954
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
87 goes into 200 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 806085.195402
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
87 goes into 260 2 times with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 806085.1954022
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 806085.1954022 with a remainder of 8.6e-07.
