Let's divide 745499 by 21
Let's see how many times 21 fits into 745499.

On to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 21

Moving on 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
Deduct 63 from 74 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 21

Step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 105 from 115, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 21

Moving on to step 4:
21 can be fit into 104 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 354.0
Deduct 84 from 104 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 21

Moving on to step 5:
If we divide 209 by 21, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 3549.0
The remainder is 20 after subtracting 189 from 209.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 21

Let's proceed to step 6:
When dividing 209 by 21, we get 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 35499.0
If we take 189 away from 209, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 21, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 35499.9
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35499.95
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 35499.952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 35499.9523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 35499.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 35499.95238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 35499.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 35499.95238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 35499.95238095 with a balance of 5e-09.
