Let's divide 20936840 by 237
We want to figure out the number of times 20936840 can be divided by 237.

Moving on to step 1:
237 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 237

On to step 2:
237 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 237

On to step 3:
The number 237 fits into 209 0 times, leaving a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 209, we get 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 237

Let's proceed to step 4:
237 can be fit into 2093 8 times, resulting in a remainder of 197.
The next digit of our result is 8. 
Result so far: 8.0
If we take 1896 away from 2093, we end up with 197.
Bring next digit (6) of the dividend behind the 197 and repeat the process: 1976 / 237

Going ahead to step 5:
The number 237 fits into 1976 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 80 after subtracting 1896 from 1976.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 237

Let's proceed to step 6:
237 goes into 808 3 times with a remainder of 97.
The next digit of our result is 3. 
Result so far: 883.0
Subtracting 711 from 808 leaves us with 97.
Include the next digit (4) from the dividend after 97, then repeat: 974 / 237

Step 7:
If we divide 974 by 237, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 8834.0
Subtract 948 from 974 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 237

Going ahead to step 8:
237 can be fit into 260 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 88341.0
Deduct 237 from 260 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
When dividing 230 by 237, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 88341.0
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
If we divide 2300 by 237, we get 9 and a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 88341.09
Subtracting 2133 from 2300 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 11:
When dividing 1670 by 237, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 88341.097
Subtracting 1659 from 1670 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 237, we get 0 and a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 88341.097
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
237 can be fit into 1100 4 times, resulting in a remainder of 152.
The next digit of our result is 4. 
Result so far: 88341.09704
Deduct 948 from 1100 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 14:
If we divide 1520 by 237, we get 6 and a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 88341.097046
Deduct 1422 from 1520 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
237 goes into 980 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 88341.0970464
The remainder is 32 after subtracting 948 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
If we divide 320 by 237, we get 1 and a remainder of 83.
The next digit of our result is 1. 
Result so far: 88341.09704641
Subtract 237 from 320 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 88341.09704641 and a remainder of 8.3e-08.
