640430 divided by 88 
Let's see how many times 88 fits into 640430.

Advancing to step 1:
The number 88 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 88

Step 2:
88 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 88

Going ahead to step 3:
If we divide 640 by 88, we get 7 and a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 616 from 640 leaves us with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 88

On to step 4:
88 goes into 244 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 176 from 244 leaves us with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 88

On to step 5:
The number 88 fits into 683 7 times, leaving a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 727.0
Deduct 616 from 683 and we're left with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 88

Let's proceed to step 6:
88 can be fit into 670 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7277.0
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
The number 88 fits into 540 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7277.6
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
120 divided by 88 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 7277.61
If we take 88 away from 120, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
88 goes into 320 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 7277.613
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
If we divide 560 by 88, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7277.6136
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 88, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 7277.61363
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
560 divided by 88 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7277.613636
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
88 goes into 320 3 times with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 7277.6136363
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
88 goes into 560 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 7277.61363636
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 7277.61363636 and a remainder of 3.2e-08.
