Let's divide 748627 by 21
We want to figure out the number of times 748627 can be divided by 21.

Let's proceed to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Let's proceed to step 2:
21 can be fit into 74 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 74, we end up with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 21

Going ahead to step 3:
If we divide 118 by 21, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 105 from 118 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 21

Going ahead to step 4:
The number 21 fits into 136 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 356.0
If we take 126 away from 136, we end up with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 21

Advancing to step 5:
If we divide 102 by 21, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 3564.0
Subtracting 84 from 102 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 21

Advancing to step 6:
The number 21 fits into 187 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 35648.0
Subtracting 168 from 187 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 35648.9
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 35648.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 35648.904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 35648.9047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 35648.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 21 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 35648.904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 35648.9047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 35648.9047619
If we take 0 away from 10, we end up 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.

In conclusion, the division gives 35648.9047619 with a balance of 1e-08.
