Let's divide 80012085 by 869
We want to figure out the number of times 80012085 can be divided by 869.

On to step 1:
869 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 869

Moving on to step 2:
The number 869 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 869

Moving on to step 3:
800 divided by 869 is 0 with a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 800 after subtracting 0 from 800.
Grab the next digit (1) from the dividend, add it to 800, then carry on: 8001 / 869

Advancing to step 4:
8001 divided by 869 is 9 with a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7821 from 8001, we get 180.
Fetch the next digit (2) from the dividend, attach it to 180 and continue: 1802 / 869

Advancing to step 5:
When dividing 1802 by 869, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtracting 1738 from 1802 leaves us with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 869

Moving on to step 6:
869 can be fit into 640 0 times, resulting in a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 920.0
If we subtract 0 from 640, we get 640.
Grab the next digit (8) from the dividend, add it to 640, then carry on: 6408 / 869

Advancing to step 7:
If we divide 6408 by 869, we get 7 and a remainder of 325.
Use 7 as the next digit of our solution. 
Result so far: 9207.0
If we subtract 6083 from 6408, we get 325.
Append the next digit (5) from the dividend to 325 and continue with: 3255 / 869

Let's proceed to step 8:
3255 divided by 869 is 3 with a remainder of 648.
The number 3 becomes the next digit in our result. 
Result so far: 92073.0
If we take 2607 away from 3255, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 9:
869 goes into 6480 7 times with a remainder of 397.
The number 7 becomes the next digit in our result. 
Result so far: 92073.7
Subtract 6083 from 6480 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 10:
3970 divided by 869 is 4 with a remainder of 494.
The next digit of our result is 4. 
Result so far: 92073.74
Deduct 3476 from 3970 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 11:
If we divide 4940 by 869, we get 5 and a remainder of 595.
The next digit of our result is 5. 
Result so far: 92073.745
Deduct 4345 from 4940 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 12:
869 can be fit into 5950 6 times, resulting in a remainder of 736.
Use 6 as the next digit of our solution. 
Result so far: 92073.7456
Deduct 5214 from 5950 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 13:
If we divide 7360 by 869, we get 8 and a remainder of 408.
Write down 8 as next digit of the result. 
Result so far: 92073.74568
The remainder is 408 after subtracting 6952 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 14:
When dividing 4080 by 869, we get 4 with a remainder of 604.
The number 4 becomes the next digit in our result. 
Result so far: 92073.745684
Deduct 3476 from 4080 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 15:
When dividing 6040 by 869, we get 6 with a remainder of 826.
Record the quotient 6 as the next digit in the result. 
Result so far: 92073.7456846
Subtract 5214 from 6040 to get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

On to step 16:
869 can be fit into 8260 9 times, resulting in a remainder of 439.
The next digit of our result is 9. 
Result so far: 92073.74568469
The remainder is 439 after subtracting 7821 from 8260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Our division results in 92073.74568469 with a remaining 4.39e-07.
