754277 divided by 21 
We're looking to find how many times 21 goes into 754277.

On to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 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
Deduct 63 from 75 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 21

Let's proceed to step 3:
The number 21 fits into 124 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 105 from 124, we get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 21

Going ahead to step 4:
192 divided by 21 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 359.0
If we subtract 189 from 192, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 21

Step 5:
When dividing 37 by 21, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 3591.0
If we subtract 21 from 37, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 21

Let's proceed to step 6:
The number 21 fits into 167 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 35917.0
If we take 147 away from 167, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 35917.9
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.

Going ahead to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 35917.95
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.

On to step 9:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 35917.952
Subtracting 42 from 50 leaves us 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.

On to step 10:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 35917.9523
If we subtract 63 from 80, we 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.

Moving on to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 35917.95238
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.

Going ahead to step 12:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 35917.95238
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 13:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 35917.9523809
Deduct 189 from 200 and we're left 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.

On to step 14:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35917.95238095
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.

The final result is 35917.95238095 with a remainder of 5e-09.
