Let's divide 423421 by 88
Let's see how many times 88 fits into 423421.

Moving on to step 1:
The number 88 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 88

Going ahead to step 2:
The number 88 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 88

On to step 3:
The number 88 fits into 423 4 times, leaving a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 352 from 423 and we're left with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 88

Going ahead to step 4:
If we divide 714 by 88, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 704 away from 714, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 88

Advancing to step 5:
88 can be fit into 102 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
If we subtract 88 from 102, we get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 88

On to step 6:
The number 88 fits into 141 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 4811.0
Subtracting 88 from 141 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
When dividing 530 by 88, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4811.6
Subtracting 528 from 530 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.

Step 8:
If we divide 20 by 88, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4811.6
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 88, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4811.602
Subtracting 176 from 200 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 88 fits into 240 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4811.6022
The remainder is 64 after subtracting 176 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 4811.6022, and the remainder is 0.00064.
