We look at the division of 4252663 by 426 
We want to figure out the number of times 4252663 can be divided by 426.

Let's proceed to step 1:
The number 426 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 426

Advancing to step 2:
426 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 426

Moving on to step 3:
The number 426 fits into 425 0 times, leaving a remainder of 425.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Fetch the next digit (2) from the dividend, attach it to 425 and continue: 4252 / 426

Moving on to step 4:
When dividing 4252 by 426, we get 9 with a remainder of 418.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3834 from 4252, we get 418.
Fetch the next digit (6) from the dividend, attach it to 418 and continue: 4186 / 426

Advancing to step 5:
426 goes into 4186 9 times with a remainder of 352.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 3834 away from 4186, we end up with 352.
Grab the next digit (6) from the dividend, add it to 352, then carry on: 3526 / 426

Let's proceed to step 6:
If we divide 3526 by 426, we get 8 and a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
Subtracting 3408 from 3526 leaves us with 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 426

Step 7:
1183 divided by 426 is 2 with a remainder of 331.
Record the quotient 2 as the next digit in the result. 
Result so far: 9982.0
If we subtract 852 from 1183, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 8:
When dividing 3310 by 426, we get 7 with a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 9982.7
The remainder is 328 after subtracting 2982 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
3280 divided by 426 is 7 with a remainder of 298.
The number 7 becomes the next digit in our result. 
Result so far: 9982.77
If we take 2982 away from 3280, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Our division results in 9982.77 with a remaining 0.298.
