We're dividing 88720104 by 855 
We want to figure out the number of times 88720104 can be divided by 855.

Step 1:
When dividing 8 by 855, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 855

Going ahead to step 2:
855 can be fit into 88 0 times, resulting in a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 855

Advancing to step 3:
855 goes into 887 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 855 from 887, we get 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 855

Moving on to step 4:
855 can be fit into 322 0 times, resulting in a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 322 to get 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 855

Moving on to step 5:
If we divide 3220 by 855, we get 3 and a remainder of 655.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 2565 from 3220 and we're left with 655.
Take the next digit (1) from the dividend and append it to 655, then repeat: 6551 / 855

Let's proceed to step 6:
855 goes into 6551 7 times with a remainder of 566.
Put 7 as the next digit of the answer. 
Result so far: 1037.0
Deduct 5985 from 6551 and we're left with 566.
Fetch the next digit (0) from the dividend, attach it to 566 and continue: 5660 / 855

Moving on to step 7:
855 can be fit into 5660 6 times, resulting in a remainder of 530.
Use 6 as the next digit of our solution. 
Result so far: 10376.0
If we take 5130 away from 5660, we end up with 530.
Take the next digit (4) from the dividend and append it to 530, then repeat: 5304 / 855

Going ahead to step 8:
5304 divided by 855 is 6 with a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 103766.0
Subtract 5130 from 5304 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
855 can be fit into 1740 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 103766.2
Subtracting 1710 from 1740 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
855 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 103766.2
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
The number 855 fits into 3000 3 times, leaving a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 103766.203
Subtracting 2565 from 3000 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 12:
855 can be fit into 4350 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 103766.2035
The remainder is 75 after subtracting 4275 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
855 can be fit into 750 0 times, resulting in a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 103766.2035
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
The number 855 fits into 7500 8 times, leaving a remainder of 660.
The number 8 becomes the next digit in our result. 
Result so far: 103766.203508
If we take 6840 away from 7500, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 15:
6600 divided by 855 is 7 with a remainder of 615.
Write down 7 as next digit of the result. 
Result so far: 103766.2035087
If we take 5985 away from 6600, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 16:
If we divide 6150 by 855, we get 7 and a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 103766.20350877
Deduct 5985 from 6150 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 103766.20350877, and the remainder is 1.65e-07.
