We divide 21421230 by 236
We're looking to find how many times 236 goes into 21421230.

Step 1:
2 divided by 236 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 236

Moving on to step 2:
If we divide 21 by 236, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 236

On to step 3:
236 can be fit into 214 0 times, resulting in a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 236

Advancing to step 4:
236 goes into 2142 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 2124 from 2142 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 236

Going ahead to step 5:
The number 236 fits into 181 0 times, leaving a remainder of 181.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 181, we get 181.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 236

On to step 6:
When dividing 1812 by 236, we get 7 with a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 907.0
Subtract 1652 from 1812 to get 160.
Grab the next digit (3) from the dividend, add it to 160, then carry on: 1603 / 236

Going ahead to step 7:
If we divide 1603 by 236, we get 6 and a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 9076.0
If we subtract 1416 from 1603, we get 187.
Bring next digit (0) of the dividend behind the 187 and repeat the process: 1870 / 236

Step 8:
236 goes into 1870 7 times with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 90767.0
The remainder is 218 after subtracting 1652 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 9:
2180 divided by 236 is 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 90767.9
If we take 2124 away from 2180, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
236 can be fit into 560 2 times, resulting in a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 90767.92
Subtract 472 from 560 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
236 goes into 880 3 times with a remainder of 172.
Use 3 as the next digit of our solution. 
Result so far: 90767.923
Subtract 708 from 880 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
When dividing 1720 by 236, we get 7 with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 90767.9237
If we subtract 1652 from 1720, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
236 can be fit into 680 2 times, resulting in a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 90767.92372
Subtract 472 from 680 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
236 goes into 2080 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 90767.923728
Deduct 1888 from 2080 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 15:
The number 236 fits into 1920 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 90767.9237288
Deduct 1888 from 1920 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 90767.9237288 with a remainder of 3.2e-07.
