Let's divide 83987378 by 855
Let's see how many times 855 fits into 83987378.

Step 1:
When dividing 8 by 855, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 855

Step 2:
83 divided by 855 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 855

Advancing to step 3:
839 divided by 855 is 0 with a remainder of 839.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 839 leaves us with 839.
Take the next digit (8) from the dividend and append it to 839, then repeat: 8398 / 855

Let's proceed to step 4:
If we divide 8398 by 855, we get 9 and a remainder of 703.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7695 from 8398, we get 703.
Take the next digit (7) from the dividend and append it to 703, then repeat: 7037 / 855

Step 5:
855 can be fit into 7037 8 times, resulting in a remainder of 197.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 6840 from 7037 and we're left with 197.
Append the next digit (3) from the dividend to 197 and continue with: 1973 / 855

Going ahead to step 6:
The number 855 fits into 1973 2 times, leaving a remainder of 263.
Record the quotient 2 as the next digit in the result. 
Result so far: 982.0
If we subtract 1710 from 1973, we get 263.
Bring next digit (7) of the dividend behind the 263 and repeat the process: 2637 / 855

Step 7:
855 goes into 2637 3 times with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 9823.0
If we take 2565 away from 2637, we end up with 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 855

Advancing to step 8:
The number 855 fits into 728 0 times, leaving a remainder of 728.
The next digit of our result is 0. 
Result so far: 98230.0
If we take 0 away from 728, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 9:
855 can be fit into 7280 8 times, resulting in a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 98230.8
Deduct 6840 from 7280 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 10:
855 goes into 4400 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 98230.85
The remainder is 125 after subtracting 4275 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
855 goes into 1250 1 times with a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 98230.851
If we subtract 855 from 1250, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 12:
855 can be fit into 3950 4 times, resulting in a remainder of 530.
Write down 4 as next digit of the result. 
Result so far: 98230.8514
If we subtract 3420 from 3950, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 13:
If we divide 5300 by 855, we get 6 and a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 98230.85146
If we take 5130 away from 5300, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
1700 divided by 855 is 1 with a remainder of 845.
Write down 1 as next digit of the result. 
Result so far: 98230.851461
If we take 855 away from 1700, we end up with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

On to step 15:
855 goes into 8450 9 times with a remainder of 755.
The number 9 becomes the next digit in our result. 
Result so far: 98230.8514619
Subtract 7695 from 8450 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 16:
If we divide 7550 by 855, we get 8 and a remainder of 710.
The next digit of our result is 8. 
Result so far: 98230.85146198
If we take 6840 away from 7550, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final result is 98230.85146198 with a remainder of 7.1e-07.
