Let's divide 20815445 by 237
We want to divide 20815445 by 237.

On to step 1:
The number 237 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 237

Advancing to step 2:
The number 237 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 237

On to step 3:
237 goes into 208 0 times with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 208, we end up with 208.
Take the next digit (1) from the dividend and append it to 208, then repeat: 2081 / 237

Let's proceed to step 4:
When dividing 2081 by 237, we get 8 with a remainder of 185.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 1896 from 2081, we get 185.
Include the next digit (5) from the dividend after 185, then repeat: 1855 / 237

Step 5:
When dividing 1855 by 237, we get 7 with a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 1659 from 1855, we get 196.
Fetch the next digit (4) from the dividend, attach it to 196 and continue: 1964 / 237

Step 6:
237 goes into 1964 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
Subtract 1896 from 1964 to get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 237

Going ahead to step 7:
The number 237 fits into 684 2 times, leaving a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 8782.0
Subtract 474 from 684 to get 210.
Fetch the next digit (5) from the dividend, attach it to 210 and continue: 2105 / 237

Step 8:
2105 divided by 237 is 8 with a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 87828.0
Subtract 1896 from 2105 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
2090 divided by 237 is 8 with a remainder of 194.
The next digit of our result is 8. 
Result so far: 87828.8
If we take 1896 away from 2090, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 10:
If we divide 1940 by 237, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 87828.88
Deduct 1896 from 1940 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 87828.88, and the remainder is 0.044.
