We look at the division of 18316831 by 870 
We're looking to find how many times 870 goes into 18316831.

Going ahead to step 1:
1 divided by 870 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 870

Advancing to step 2:
870 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 870

Step 3:
When dividing 183 by 870, we get 0 with a remainder of 183.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Grab the next digit (1) from the dividend, add it to 183, then carry on: 1831 / 870

Moving on to step 4:
870 goes into 1831 2 times with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1740 from 1831 and we're left with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 870

On to step 5:
The number 870 fits into 916 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 46 after subtracting 870 from 916.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 870

Advancing to step 6:
468 divided by 870 is 0 with a remainder of 468.
Write down 0 as next digit of the result. 
Result so far: 210.0
Deduct 0 from 468 and we're left with 468.
Append the next digit (3) from the dividend to 468 and continue with: 4683 / 870

Moving on to step 7:
The number 870 fits into 4683 5 times, leaving a remainder of 333.
Use 5 as the next digit of our solution. 
Result so far: 2105.0
If we take 4350 away from 4683, we end up with 333.
Take the next digit (1) from the dividend and append it to 333, then repeat: 3331 / 870

Going ahead to step 8:
3331 divided by 870 is 3 with a remainder of 721.
Put 3 as the next digit of the answer. 
Result so far: 21053.0
If we take 2610 away from 3331, we end up with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Advancing to step 9:
870 goes into 7210 8 times with a remainder of 250.
Put 8 as the next digit of the answer. 
Result so far: 21053.8
Subtract 6960 from 7210 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
870 goes into 2500 2 times with a remainder of 760.
The number 2 becomes the next digit in our result. 
Result so far: 21053.82
Subtract 1740 from 2500 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 11:
7600 divided by 870 is 8 with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 21053.828
If we subtract 6960 from 7600, 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.

Let's proceed to step 12:
6400 divided by 870 is 7 with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 21053.8287
Deduct 6090 from 6400 and we're left 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.

On to step 13:
If we divide 3100 by 870, we get 3 and a remainder of 490.
Put 3 as the next digit of the answer. 
Result so far: 21053.82873
Subtract 2610 from 3100 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 14:
When dividing 4900 by 870, we get 5 with a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 21053.828735
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.

Advancing to step 15:
When dividing 5500 by 870, we get 6 with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 21053.8287356
The remainder is 280 after subtracting 5220 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 16:
If we divide 2800 by 870, we get 3 and a remainder of 190.
The number 3 becomes the next digit in our result. 
Result so far: 21053.82873563
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.

The quotient of the division is 21053.82873563, and the remainder is 1.9e-07.
