85672270 ÷ 870 
Our goal is to divide 85672270 by 870.

Let's proceed to step 1:
When dividing 8 by 870, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 870

Let's proceed to step 2:
870 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 870

Step 3:
870 goes into 856 0 times with a remainder of 856.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 856 to get 856.
Grab the next digit (7) from the dividend, add it to 856, then carry on: 8567 / 870

Going ahead to step 4:
870 goes into 8567 9 times with a remainder of 737.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7830 from 8567 to get 737.
Append the next digit (2) from the dividend to 737 and continue with: 7372 / 870

On to step 5:
If we divide 7372 by 870, we get 8 and a remainder of 412.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 6960 from 7372 to get 412.
Bring next digit (2) of the dividend behind the 412 and repeat the process: 4122 / 870

Going ahead to step 6:
If we divide 4122 by 870, we get 4 and a remainder of 642.
Use 4 as the next digit of our solution. 
Result so far: 984.0
Subtracting 3480 from 4122 leaves us with 642.
Include the next digit (7) from the dividend after 642, then repeat: 6427 / 870

On to step 7:
If we divide 6427 by 870, we get 7 and a remainder of 337.
The next digit of our result is 7. 
Result so far: 9847.0
Subtract 6090 from 6427 to get 337.
Bring next digit (0) of the dividend behind the 337 and repeat the process: 3370 / 870

Advancing to step 8:
870 goes into 3370 3 times with a remainder of 760.
Write down 3 as next digit of the result. 
Result so far: 98473.0
Deduct 2610 from 3370 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 9:
870 can be fit into 7600 8 times, resulting in a remainder of 640.
The next digit of our result is 8. 
Result so far: 98473.8
Subtracting 6960 from 7600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
6400 divided by 870 is 7 with a remainder of 310.
Record the quotient 7 as the next digit in the result. 
Result so far: 98473.87
If we subtract 6090 from 6400, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 11:
When dividing 3100 by 870, we get 3 with a remainder of 490.
Use 3 as the next digit of our solution. 
Result so far: 98473.873
Deduct 2610 from 3100 and we're left 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.

Going ahead to step 12:
870 goes into 4900 5 times with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 98473.8735
If we take 4350 away from 4900, we end up 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.

On to step 13:
If we divide 5500 by 870, we get 6 and a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 98473.87356
Deduct 5220 from 5500 and we're left 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:
870 goes into 2800 3 times with a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 98473.873563
If we take 2610 away from 2800, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 15:
1900 divided by 870 is 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 98473.8735632
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.

Let's proceed to step 16:
If we divide 1600 by 870, we get 1 and a remainder of 730.
Write down 1 as next digit of the result. 
Result so far: 98473.87356321
Subtracting 870 from 1600 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

The quotient of the division is 98473.87356321, and the remainder is 7.3e-07.
