We look at the division of 21999631 by 288 
We're looking to find how many times 288 goes into 21999631.

Going ahead to step 1:
If we divide 2 by 288, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 288

Moving on to step 2:
If we divide 21 by 288, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 288

Going ahead to step 3:
If we divide 219 by 288, we get 0 and a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Fetch the next digit (9) from the dividend, attach it to 219 and continue: 2199 / 288

Advancing to step 4:
288 goes into 2199 7 times with a remainder of 183.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 2016 from 2199 and we're left with 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 288

Advancing to step 5:
If we divide 1839 by 288, we get 6 and a remainder of 111.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we take 1728 away from 1839, we end up with 111.
Append the next digit (6) from the dividend to 111 and continue with: 1116 / 288

Step 6:
288 goes into 1116 3 times with a remainder of 252.
Write down 3 as next digit of the result. 
Result so far: 763.0
The remainder is 252 after subtracting 864 from 1116.
Grab the next digit (3) from the dividend, add it to 252, then carry on: 2523 / 288

Moving on to step 7:
The number 288 fits into 2523 8 times, leaving a remainder of 219.
Put 8 as the next digit of the answer. 
Result so far: 7638.0
If we subtract 2304 from 2523, we get 219.
Include the next digit (1) from the dividend after 219, then repeat: 2191 / 288

Step 8:
2191 divided by 288 is 7 with a remainder of 175.
The next digit of our result is 7. 
Result so far: 76387.0
Subtract 2016 from 2191 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 9:
When dividing 1750 by 288, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 76387.6
Subtracting 1728 from 1750 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 288, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 76387.6
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
The number 288 fits into 2200 7 times, leaving a remainder of 184.
The next digit of our result is 7. 
Result so far: 76387.607
Deduct 2016 from 2200 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
When dividing 1840 by 288, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 76387.6076
Subtract 1728 from 1840 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
288 goes into 1120 3 times with a remainder of 256.
Record the quotient 3 as the next digit in the result. 
Result so far: 76387.60763
The remainder is 256 after subtracting 864 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
When dividing 2560 by 288, we get 8 with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 76387.607638
If we take 2304 away from 2560, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
When dividing 2560 by 288, we get 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 76387.6076388
The remainder is 256 after subtracting 2304 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 76387.6076388 and a remainder of 2.56e-06.
