77416900 ÷ 855 
We want to figure out the number of times 77416900 can be divided by 855.

Going ahead to step 1:
The number 855 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 855

Step 2:
If we divide 77 by 855, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 855

Going ahead to step 3:
855 can be fit into 774 0 times, resulting in a remainder of 774.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 774 after subtracting 0 from 774.
Append the next digit (1) from the dividend to 774 and continue with: 7741 / 855

On to step 4:
When dividing 7741 by 855, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7695 from 7741 to get 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 855

Step 5:
855 can be fit into 466 0 times, resulting in a remainder of 466.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 466 leaves us with 466.
Include the next digit (9) from the dividend after 466, then repeat: 4669 / 855

Advancing to step 6:
If we divide 4669 by 855, we get 5 and a remainder of 394.
Put 5 as the next digit of the answer. 
Result so far: 905.0
The remainder is 394 after subtracting 4275 from 4669.
Append the next digit (0) from the dividend to 394 and continue with: 3940 / 855

Advancing to step 7:
3940 divided by 855 is 4 with a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 9054.0
If we take 3420 away from 3940, we end up with 520.
Grab the next digit (0) from the dividend, add it to 520, then carry on: 5200 / 855

Let's proceed to step 8:
The number 855 fits into 5200 6 times, leaving a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 90546.0
Subtracting 5130 from 5200 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
The number 855 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 90546.0
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 10:
The number 855 fits into 7000 8 times, leaving a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 90546.08
Subtracting 6840 from 7000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
The number 855 fits into 1600 1 times, leaving a remainder of 745.
Use 1 as the next digit of our solution. 
Result so far: 90546.081
Subtracting 855 from 1600 leaves us with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

On to step 12:
855 can be fit into 7450 8 times, resulting in a remainder of 610.
The next digit of our result is 8. 
Result so far: 90546.0818
If we take 6840 away from 7450, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 13:
If we divide 6100 by 855, we get 7 and a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 90546.08187
Subtract 5985 from 6100 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 14:
1150 divided by 855 is 1 with a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 90546.081871
The remainder is 295 after subtracting 855 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 15:
If we divide 2950 by 855, we get 3 and a remainder of 385.
The next digit of our result is 3. 
Result so far: 90546.0818713
If we subtract 2565 from 2950, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 16:
The number 855 fits into 3850 4 times, leaving a remainder of 430.
The number 4 becomes the next digit in our result. 
Result so far: 90546.08187134
Subtract 3420 from 3850 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

After the division, we end up with 90546.08187134 and a remainder of 4.3e-07.
