We divide 620431 by 88
We're looking to find how many times 88 goes into 620431.

Advancing to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 88

On to step 2:
If we divide 62 by 88, we get 0 and a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 88

Advancing to step 3:
88 can be fit into 620 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 4 after subtracting 616 from 620.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 88

Moving on to step 4:
The number 88 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 44 after subtracting 0 from 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 88

On to step 5:
88 goes into 443 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 705.0
The remainder is 3 after subtracting 440 from 443.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 88

On to step 6:
When dividing 31 by 88, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 7050.0
Subtract 0 from 31 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
If we divide 310 by 88, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 7050.3
If we take 264 away from 310, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
When dividing 460 by 88, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7050.35
The remainder is 20 after subtracting 440 from 460.
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 9:
When dividing 200 by 88, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 7050.352
If we subtract 176 from 200, we get 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:
240 divided by 88 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 7050.3522
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 final result is 7050.3522 with a remainder of 0.00064.
