We look at the division of 750746 by 21 
Let's see how many times 21 fits into 750746.

Moving on to step 1:
7 divided by 21 is 0 with 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.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 21

Moving on to step 2:
When dividing 75 by 21, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 75 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 21

Moving on to step 3:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 105 from 120 and we're left with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 21

Step 4:
If we divide 157 by 21, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 357.0
Subtract 147 from 157 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 21

Advancing to step 5:
When dividing 104 by 21, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3574.0
Subtracting 84 from 104 leaves us with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 21

Going ahead to step 6:
21 can be fit into 206 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 35749.0
Subtract 189 from 206 to 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.

Let's proceed to step 7:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 35749.8
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 35749.8
Subtract 0 from 20 to 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.

Advancing to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 35749.809
Subtract 189 from 200 to 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 10:
110 divided by 21 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 35749.8095
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.

Step 11:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 35749.80952
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.

Let's proceed to step 12:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 35749.809523
Deduct 63 from 80 and we're left with 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 13:
21 goes into 170 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 35749.8095238
Deduct 168 from 170 and we're left with 2.
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 14:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 35749.8095238
Subtract 0 from 20 to 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.

Our division results in 35749.8095238 with a remaining 2e-08.
