85613485 ÷ 870 
We want to divide 85613485 by 870.

Moving on to step 1:
The number 870 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 870

Step 2:
870 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 870

Let's proceed to step 3:
870 can be fit into 856 0 times, resulting in a remainder of 856.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 856, we end up with 856.
Append the next digit (1) from the dividend to 856 and continue with: 8561 / 870

Let's proceed to step 4:
When dividing 8561 by 870, we get 9 with a remainder of 731.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7830 from 8561, we get 731.
Grab the next digit (3) from the dividend, add it to 731, then carry on: 7313 / 870

Step 5:
870 can be fit into 7313 8 times, resulting in a remainder of 353.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 6960 from 7313 leaves us with 353.
Fetch the next digit (4) from the dividend, attach it to 353 and continue: 3534 / 870

Going ahead to step 6:
If we divide 3534 by 870, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 984.0
If we take 3480 away from 3534, we end up with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 870

On to step 7:
If we divide 548 by 870, we get 0 and a remainder of 548.
The number 0 becomes the next digit in our result. 
Result so far: 9840.0
Subtracting 0 from 548 leaves us with 548.
Fetch the next digit (5) from the dividend, attach it to 548 and continue: 5485 / 870

Advancing to step 8:
If we divide 5485 by 870, we get 6 and a remainder of 265.
Use 6 as the next digit of our solution. 
Result so far: 98406.0
The remainder is 265 after subtracting 5220 from 5485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
2650 divided by 870 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 98406.3
Deduct 2610 from 2650 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
The number 870 fits into 400 0 times, leaving a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 98406.3
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
When dividing 4000 by 870, we get 4 with a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 98406.304
If we subtract 3480 from 4000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
If we divide 5200 by 870, we get 5 and a remainder of 850.
Record the quotient 5 as the next digit in the result. 
Result so far: 98406.3045
If we subtract 4350 from 5200, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Advancing to step 13:
8500 divided by 870 is 9 with a remainder of 670.
Write down 9 as next digit of the result. 
Result so far: 98406.30459
The remainder is 670 after subtracting 7830 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 14:
When dividing 6700 by 870, we get 7 with a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 98406.304597
If we subtract 6090 from 6700, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 15:
870 goes into 6100 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 98406.3045977
Subtract 6090 from 6100 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.

In conclusion, the division gives 98406.3045977 with a balance of 1e-07.
