746152 ÷ 21 
Our goal is to divide 746152 by 21.

Advancing 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
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 21

Let's proceed to step 2:
When dividing 74 by 21, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 63 from 74 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 21

On to step 3:
The number 21 fits into 116 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 105 from 116, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 21

Advancing to step 4:
111 divided by 21 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we subtract 105 from 111, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 21

Let's proceed to step 5:
When dividing 65 by 21, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3553.0
The remainder is 2 after subtracting 63 from 65.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

On to step 6:
21 goes into 22 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 35531.0
If we subtract 21 from 22, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 35531.0
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.

On to step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 35531.04
The remainder is 16 after subtracting 84 from 100.
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 9:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 35531.047
Deduct 147 from 160 and we're left 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.

Advancing to step 10:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 35531.0476
Subtracting 126 from 130 leaves us 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.

Step 11:
21 goes into 40 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 35531.04761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 35531.047619
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.

Going ahead to step 13:
10 divided by 21 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 35531.047619
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 14:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 35531.04761904
If we take 84 away from 100, we end up 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.

The final result is 35531.04761904 with a remainder of 1.6e-08.
