We're dividing 951257 by 21 
Our goal is to divide 951257 by 21.

Going ahead to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 21

Let's proceed to step 2:
The number 21 fits into 95 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 95, we end up with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 21

Going ahead to step 3:
111 divided by 21 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 105 from 111 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 21

Going ahead to step 4:
62 divided by 21 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 21

On to step 5:
The number 21 fits into 205 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 4529.0
If we take 189 away from 205, we end up with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 21

Let's proceed to step 6:
21 can be fit into 167 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 45297.0
Subtract 147 from 167 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 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 45297.9
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.

Moving on to step 8:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 45297.95
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.

Going ahead to step 9:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 45297.952
If we take 42 away from 50, we end up 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.

Advancing to step 10:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 45297.9523
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.

Let's proceed to step 11:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 45297.95238
Subtract 168 from 170 to 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 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: 45297.95238
Subtracting 0 from 20 leaves us 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.

On to step 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 45297.9523809
If we subtract 189 from 200, we 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.

Moving on to step 14:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 45297.95238095
If we subtract 105 from 110, we get 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 45297.95238095 with a remainder of 5e-09.
