Let's divide 21013089 by 588
We're looking to find how many times 588 goes into 21013089.

On to step 1:
588 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 588

On to step 2:
588 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 588

Let's proceed to step 3:
The number 588 fits into 210 0 times, leaving a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Grab the next digit (1) from the dividend, add it to 210, then carry on: 2101 / 588

Let's proceed to step 4:
The number 588 fits into 2101 3 times, leaving a remainder of 337.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1764 from 2101, we get 337.
Grab the next digit (3) from the dividend, add it to 337, then carry on: 3373 / 588

Let's proceed to step 5:
588 can be fit into 3373 5 times, resulting in a remainder of 433.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 2940 from 3373 leaves us with 433.
Append the next digit (0) from the dividend to 433 and continue with: 4330 / 588

On to step 6:
4330 divided by 588 is 7 with a remainder of 214.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
Deduct 4116 from 4330 and we're left with 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 588

Going ahead to step 7:
The number 588 fits into 2148 3 times, leaving a remainder of 384.
Put 3 as the next digit of the answer. 
Result so far: 3573.0
Deduct 1764 from 2148 and we're left with 384.
Fetch the next digit (9) from the dividend, attach it to 384 and continue: 3849 / 588

Let's proceed to step 8:
If we divide 3849 by 588, we get 6 and a remainder of 321.
Record the quotient 6 as the next digit in the result. 
Result so far: 35736.0
If we take 3528 away from 3849, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 9:
The number 588 fits into 3210 5 times, leaving a remainder of 270.
The next digit of our result is 5. 
Result so far: 35736.5
Subtract 2940 from 3210 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
If we divide 2700 by 588, we get 4 and a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 35736.54
If we take 2352 away from 2700, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
When dividing 3480 by 588, we get 5 with a remainder of 540.
Put 5 as the next digit of the answer. 
Result so far: 35736.545
If we subtract 2940 from 3480, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 12:
The number 588 fits into 5400 9 times, leaving a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 35736.5459
Deduct 5292 from 5400 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
When dividing 1080 by 588, we get 1 with a remainder of 492.
Put 1 as the next digit of the answer. 
Result so far: 35736.54591
The remainder is 492 after subtracting 588 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 14:
588 can be fit into 4920 8 times, resulting in a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 35736.545918
If we subtract 4704 from 4920, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
2160 divided by 588 is 3 with a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 35736.5459183
Subtract 1764 from 2160 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 16:
3960 divided by 588 is 6 with a remainder of 432.
Write down 6 as next digit of the result. 
Result so far: 35736.54591836
Subtracting 3528 from 3960 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

After the division, we end up with 35736.54591836 and a remainder of 4.32e-07.
