21635759 ÷ 238 
We want to divide 21635759 by 238.

Step 1:
If we divide 2 by 238, we get 0 and 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 238

On to step 2:
The number 238 fits into 21 0 times, leaving 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.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 238

Moving on to step 3:
The number 238 fits into 216 0 times, leaving a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Append the next digit (3) from the dividend to 216 and continue with: 2163 / 238

Advancing to step 4:
2163 divided by 238 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 9.0
If we take 2142 away from 2163, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 238

Step 5:
When dividing 215 by 238, we get 0 with a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 215 after subtracting 0 from 215.
Grab the next digit (7) from the dividend, add it to 215, then carry on: 2157 / 238

On to step 6:
If we divide 2157 by 238, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 909.0
Subtracting 2142 from 2157 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 238

On to step 7:
155 divided by 238 is 0 with a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 9090.0
Subtracting 0 from 155 leaves us with 155.
Take the next digit (9) from the dividend and append it to 155, then repeat: 1559 / 238

Step 8:
If we divide 1559 by 238, we get 6 and a remainder of 131.
The next digit of our result is 6. 
Result so far: 90906.0
Subtract 1428 from 1559 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 9:
238 can be fit into 1310 5 times, resulting in a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 90906.5
If we subtract 1190 from 1310, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
If we divide 1200 by 238, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 90906.55
Subtracting 1190 from 1200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 90906.55, and the remainder is 0.01.
