We're dividing 78367221 by 855 
Our goal is to divide 78367221 by 855.

On to step 1:
7 divided by 855 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 855

Advancing to step 2:
When dividing 78 by 855, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 855

Advancing to step 3:
The number 855 fits into 783 0 times, leaving a remainder of 783.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 783 to get 783.
Append the next digit (6) from the dividend to 783 and continue with: 7836 / 855

Advancing to step 4:
855 goes into 7836 9 times with a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7695 from 7836 leaves us with 141.
Fetch the next digit (7) from the dividend, attach it to 141 and continue: 1417 / 855

Step 5:
When dividing 1417 by 855, we get 1 with a remainder of 562.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 562 after subtracting 855 from 1417.
Grab the next digit (2) from the dividend, add it to 562, then carry on: 5622 / 855

Let's proceed to step 6:
If we divide 5622 by 855, we get 6 and a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 916.0
If we take 5130 away from 5622, we end up with 492.
Bring next digit (2) of the dividend behind the 492 and repeat the process: 4922 / 855

Going ahead to step 7:
4922 divided by 855 is 5 with a remainder of 647.
The number 5 becomes the next digit in our result. 
Result so far: 9165.0
Deduct 4275 from 4922 and we're left with 647.
Fetch the next digit (1) from the dividend, attach it to 647 and continue: 6471 / 855

Let's proceed to step 8:
6471 divided by 855 is 7 with a remainder of 486.
The next digit of our result is 7. 
Result so far: 91657.0
The remainder is 486 after subtracting 5985 from 6471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 9:
855 can be fit into 4860 5 times, resulting in a remainder of 585.
The next digit of our result is 5. 
Result so far: 91657.5
If we subtract 4275 from 4860, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

On to step 10:
The number 855 fits into 5850 6 times, leaving a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 91657.56
If we take 5130 away from 5850, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 11:
If we divide 7200 by 855, we get 8 and a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 91657.568
Subtracting 6840 from 7200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
3600 divided by 855 is 4 with a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 91657.5684
Subtracting 3420 from 3600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
855 goes into 1800 2 times with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 91657.56842
If we take 1710 away from 1800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
The number 855 fits into 900 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 91657.568421
Subtract 855 from 900 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 15:
When dividing 450 by 855, we get 0 with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 91657.568421
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
When dividing 4500 by 855, we get 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 91657.56842105
Subtract 4275 from 4500 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 91657.56842105 with a balance of 2.25e-07.
