83574965 ÷ 855 
We want to figure out the number of times 83574965 can be divided by 855.

Let's proceed to step 1:
The number 855 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 855

Advancing to step 2:
The number 855 fits into 83 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 855

Going ahead to step 3:
If we divide 835 by 855, we get 0 and a remainder of 835.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 835 to get 835.
Append the next digit (7) from the dividend to 835 and continue with: 8357 / 855

Advancing to step 4:
8357 divided by 855 is 9 with a remainder of 662.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7695 from 8357 and we're left with 662.
Fetch the next digit (4) from the dividend, attach it to 662 and continue: 6624 / 855

Step 5:
If we divide 6624 by 855, we get 7 and a remainder of 639.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 639 after subtracting 5985 from 6624.
Fetch the next digit (9) from the dividend, attach it to 639 and continue: 6399 / 855

Moving on to step 6:
When dividing 6399 by 855, we get 7 with a remainder of 414.
Write down 7 as next digit of the result. 
Result so far: 977.0
Subtract 5985 from 6399 to get 414.
Append the next digit (6) from the dividend to 414 and continue with: 4146 / 855

Step 7:
4146 divided by 855 is 4 with a remainder of 726.
Record the quotient 4 as the next digit in the result. 
Result so far: 9774.0
Deduct 3420 from 4146 and we're left with 726.
Take the next digit (5) from the dividend and append it to 726, then repeat: 7265 / 855

Step 8:
855 can be fit into 7265 8 times, resulting in a remainder of 425.
Put 8 as the next digit of the answer. 
Result so far: 97748.0
Deduct 6840 from 7265 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 9:
855 goes into 4250 4 times with a remainder of 830.
Put 4 as the next digit of the answer. 
Result so far: 97748.4
Subtracting 3420 from 4250 leaves us with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 10:
The number 855 fits into 8300 9 times, leaving a remainder of 605.
Record the quotient 9 as the next digit in the result. 
Result so far: 97748.49
Subtracting 7695 from 8300 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Step 11:
855 can be fit into 6050 7 times, resulting in a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 97748.497
Subtracting 5985 from 6050 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
855 can be fit into 650 0 times, resulting in a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 97748.497
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
855 can be fit into 6500 7 times, resulting in a remainder of 515.
Use 7 as the next digit of our solution. 
Result so far: 97748.49707
If we take 5985 away from 6500, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 14:
The number 855 fits into 5150 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 97748.497076
Deduct 5130 from 5150 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
If we divide 200 by 855, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 97748.497076
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
855 goes into 2000 2 times with a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 97748.49707602
If we take 1710 away from 2000, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final result is 97748.49707602 with a remainder of 2.9e-07.
