We're dividing 86450103 by 855 
We want to figure out the number of times 86450103 can be divided by 855.

Going ahead to step 1:
855 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 855

Step 2:
86 divided by 855 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 855

Step 3:
When dividing 864 by 855, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 855 from 864 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 855

Step 4:
When dividing 95 by 855, we get 0 with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 95 to get 95.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 855

Step 5:
If we divide 950 by 855, we get 1 and a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 855 from 950 leaves us with 95.
Take the next digit (1) from the dividend and append it to 95, then repeat: 951 / 855

Moving on to step 6:
855 goes into 951 1 times with a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 1011.0
The remainder is 96 after subtracting 855 from 951.
Fetch the next digit (0) from the dividend, attach it to 96 and continue: 960 / 855

Let's proceed to step 7:
960 divided by 855 is 1 with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 10111.0
If we subtract 855 from 960, we get 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 855

Going ahead to step 8:
855 can be fit into 1053 1 times, resulting in a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 101111.0
Subtract 855 from 1053 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 9:
1980 divided by 855 is 2 with a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 101111.2
If we take 1710 away from 1980, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
855 goes into 2700 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 101111.23
Deduct 2565 from 2700 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
855 can be fit into 1350 1 times, resulting in a remainder of 495.
The number 1 becomes the next digit in our result. 
Result so far: 101111.231
Subtracting 855 from 1350 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 12:
4950 divided by 855 is 5 with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 101111.2315
Deduct 4275 from 4950 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 13:
6750 divided by 855 is 7 with a remainder of 765.
The number 7 becomes the next digit in our result. 
Result so far: 101111.23157
Deduct 5985 from 6750 and we're left with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 14:
7650 divided by 855 is 8 with a remainder of 810.
The number 8 becomes the next digit in our result. 
Result so far: 101111.231578
If we subtract 6840 from 7650, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 15:
8100 divided by 855 is 9 with a remainder of 405.
Write down 9 as next digit of the result. 
Result so far: 101111.2315789
The remainder is 405 after subtracting 7695 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 16:
4050 divided by 855 is 4 with a remainder of 630.
Record the quotient 4 as the next digit in the result. 
Result so far: 101111.23157894
Subtracting 3420 from 4050 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The final outcome is 101111.23157894, with a leftover of 6.3e-07.
