Let's divide 830420 by 88
We're looking to find how many times 88 goes into 830420.

On to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 88

Step 2:
88 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 88

Step 3:
When dividing 830 by 88, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 792 from 830 to get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 88

Step 4:
88 can be fit into 384 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtracting 352 from 384 leaves us with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 88

Step 5:
If we divide 322 by 88, we get 3 and a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 943.0
Subtracting 264 from 322 leaves us with 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 88

Advancing to step 6:
If we divide 580 by 88, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 9436.0
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
If we divide 520 by 88, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 9436.5
Deduct 440 from 520 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
When dividing 800 by 88, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9436.59
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 88 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9436.59
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
88 can be fit into 800 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9436.5909
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 88, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 9436.5909
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
88 can be fit into 800 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9436.590909
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 88 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 9436.590909
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 88 fits into 800 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9436.59090909
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 9436.59090909 and a remainder of 8e-09.
