Let's divide 746350 by 21
We want to divide 746350 by 21.

Going ahead to step 1:
7 divided by 21 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 21

Step 2:
21 goes into 74 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 11 after subtracting 63 from 74.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 21

Going ahead to step 3:
116 divided by 21 is 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 105 from 116 leaves us with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 21

On to step 4:
The number 21 fits into 113 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Subtracting 105 from 113 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 21

On to step 5:
21 goes into 85 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 3554.0
Deduct 84 from 85 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 21

Advancing to step 6:
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: 35540.0
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.

On to step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 35540.4
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.

Moving on to step 8:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 35540.47
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.

Going ahead to step 9:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 35540.476
Deduct 126 from 130 and we're left 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.

On to step 10:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 35540.4761
The remainder is 19 after subtracting 21 from 40.
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 11:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 35540.47619
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.

Let's proceed to step 12:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 35540.47619
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.

Step 13:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 35540.4761904
Subtract 84 from 100 to 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 14:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 35540.47619047
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.

After the division, we end up with 35540.47619047 and a remainder of 1.3e-08.
