751175 divided by 21 
Let's see how many times 21 fits into 751175.

Advancing to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

On to step 2:
21 can be fit into 75 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 63 from 75 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 21

Moving on to step 3:
When dividing 121 by 21, we get 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 35.0
If we take 105 away from 121, we end up with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 21

Moving on to step 4:
21 goes into 161 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 357.0
Deduct 147 from 161 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 21

On to step 5:
21 can be fit into 147 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 3577.0
If we subtract 147 from 147, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 21

Let's proceed to step 6:
21 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 35770.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 35770.2
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 35770.23
Subtract 63 from 80 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.

Advancing to step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 35770.238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 35770.238
If we subtract 0 from 20, we 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.

Let's proceed to step 11:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 35770.23809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 35770.238095
Deduct 105 from 110 and we're left 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.

Going ahead to step 13:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 35770.2380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 35770.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 35770.23809523 with a remainder of 1.7e-08.
