745930 ÷ 21 
We want to figure out the number of times 745930 can be divided by 21.

Moving on to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 21

Let's proceed to step 2:
The number 21 fits into 74 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 63 from 74 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 21

On to step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 10 after subtracting 105 from 115.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 21

Step 4:
21 can be fit into 109 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 355.0
Subtracting 105 from 109 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 21

Let's proceed to step 5:
If we divide 43 by 21, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 3552.0
The remainder is 1 after subtracting 42 from 43.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 21

Moving on to step 6:
When dividing 10 by 21, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 35520.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 35520.4
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 35520.47
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 35520.476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 35520.4761
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.

Step 11:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 35520.47619
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.

On to step 12:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 35520.47619
Deduct 0 from 10 and we're left 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.

Let's proceed to step 13:
21 goes into 100 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 35520.4761904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 35520.47619047
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.

In conclusion, the division gives 35520.47619047 with a balance of 1.3e-08.
