We look at the division of 21426766 by 425 
We're looking to find how many times 425 goes into 21426766.

Step 1:
If we divide 2 by 425, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 425

Going ahead to step 2:
21 divided by 425 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 425

Going ahead to step 3:
If we divide 214 by 425, we get 0 and a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Take the next digit (2) from the dividend and append it to 214, then repeat: 2142 / 425

On to step 4:
When dividing 2142 by 425, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 2125 from 2142 to get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 425

On to step 5:
425 can be fit into 176 0 times, resulting in a remainder of 176.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 176, we end up with 176.
Take the next digit (7) from the dividend and append it to 176, then repeat: 1767 / 425

Going ahead to step 6:
The number 425 fits into 1767 4 times, leaving a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 504.0
Deduct 1700 from 1767 and we're left with 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 425

Advancing to step 7:
425 goes into 676 1 times with a remainder of 251.
The next digit of our result is 1. 
Result so far: 5041.0
The remainder is 251 after subtracting 425 from 676.
Append the next digit (6) from the dividend to 251 and continue with: 2516 / 425

Step 8:
The number 425 fits into 2516 5 times, leaving a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 50415.0
The remainder is 391 after subtracting 2125 from 2516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 9:
If we divide 3910 by 425, we get 9 and a remainder of 85.
The next digit of our result is 9. 
Result so far: 50415.9
Deduct 3825 from 3910 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
850 divided by 425 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 50415.92
Deduct 850 from 850 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 425, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 50415.92
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
When dividing 0 by 425, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50415.92
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 50415.92, and the remainder is 0.0.
