87485128 divided by 807 
We want to divide 87485128 by 807.

Advancing to step 1:
The number 807 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 807

Moving on to step 2:
807 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (4) of the dividend behind the 87 and repeat the process: 874 / 807

Going ahead to step 3:
When dividing 874 by 807, we get 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 807 from 874 leaves us with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 807

Step 4:
The number 807 fits into 678 0 times, leaving a remainder of 678.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 678 after subtracting 0 from 678.
Grab the next digit (5) from the dividend, add it to 678, then carry on: 6785 / 807

Moving on to step 5:
When dividing 6785 by 807, we get 8 with a remainder of 329.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 329 after subtracting 6456 from 6785.
Include the next digit (1) from the dividend after 329, then repeat: 3291 / 807

On to step 6:
If we divide 3291 by 807, we get 4 and a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 1084.0
Subtracting 3228 from 3291 leaves us with 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 807

Moving on to step 7:
807 can be fit into 632 0 times, resulting in a remainder of 632.
Put 0 as the next digit of the answer. 
Result so far: 10840.0
Subtract 0 from 632 to get 632.
Bring next digit (8) of the dividend behind the 632 and repeat the process: 6328 / 807

Advancing to step 8:
807 goes into 6328 7 times with a remainder of 679.
Use 7 as the next digit of our solution. 
Result so far: 108407.0
Subtracting 5649 from 6328 leaves us with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 9:
If we divide 6790 by 807, we get 8 and a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 108407.8
If we subtract 6456 from 6790, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 10:
The number 807 fits into 3340 4 times, leaving a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 108407.84
If we subtract 3228 from 3340, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
If we divide 1120 by 807, we get 1 and a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 108407.841
The remainder is 313 after subtracting 807 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 12:
When dividing 3130 by 807, we get 3 with a remainder of 709.
Record the quotient 3 as the next digit in the result. 
Result so far: 108407.8413
Deduct 2421 from 3130 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Going ahead to step 13:
7090 divided by 807 is 8 with a remainder of 634.
The number 8 becomes the next digit in our result. 
Result so far: 108407.84138
Deduct 6456 from 7090 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 14:
807 can be fit into 6340 7 times, resulting in a remainder of 691.
The number 7 becomes the next digit in our result. 
Result so far: 108407.841387
If we subtract 5649 from 6340, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 15:
When dividing 6910 by 807, we get 8 with a remainder of 454.
The next digit of our result is 8. 
Result so far: 108407.8413878
If we take 6456 away from 6910, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 16:
807 can be fit into 4540 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 108407.84138785
The remainder is 505 after subtracting 4035 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

In conclusion, the division gives 108407.84138785 with a balance of 5.05e-07.
