We look at the division of 756034 by 21 
Our goal is to divide 756034 by 21.

Advancing to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

Advancing to step 2:
If we divide 75 by 21, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 75 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 21

On to step 3:
When dividing 126 by 21, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 0 after subtracting 126 from 126.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 21

Moving on to step 4:
21 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 360.0
If we subtract 0 from 0, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

Let's proceed to step 5:
3 divided by 21 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 3600.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 21

On to step 6:
The number 21 fits into 34 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 36001.0
Deduct 21 from 34 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.

Going ahead to step 7:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 36001.6
Subtract 126 from 130 to get 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 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 36001.61
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.

Let's proceed to step 9:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 36001.619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 36001.619
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.

Advancing to step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 36001.61904
Subtracting 84 from 100 leaves us 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.

Advancing to step 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 36001.619047
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.

Advancing to step 13:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 36001.6190476
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.

Let's proceed to step 14:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 36001.61904761
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.

The quotient of the division is 36001.61904761, and the remainder is 1.9e-08.
