Let's divide 81234179 by 869
Let's see how many times 869 fits into 81234179.

On to step 1:
If we divide 8 by 869, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 869

Going ahead to step 2:
81 divided by 869 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 869

Let's proceed to step 3:
869 goes into 812 0 times with a remainder of 812.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 812 and we're left with 812.
Append the next digit (3) from the dividend to 812 and continue with: 8123 / 869

Moving on to step 4:
869 can be fit into 8123 9 times, resulting in a remainder of 302.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7821 away from 8123, we end up with 302.
Fetch the next digit (4) from the dividend, attach it to 302 and continue: 3024 / 869

Going ahead to step 5:
If we divide 3024 by 869, we get 3 and a remainder of 417.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we take 2607 away from 3024, we end up with 417.
Fetch the next digit (1) from the dividend, attach it to 417 and continue: 4171 / 869

Advancing to step 6:
4171 divided by 869 is 4 with a remainder of 695.
Write down 4 as next digit of the result. 
Result so far: 934.0
The remainder is 695 after subtracting 3476 from 4171.
Append the next digit (7) from the dividend to 695 and continue with: 6957 / 869

On to step 7:
869 can be fit into 6957 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 9348.0
Subtracting 6952 from 6957 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 869

On to step 8:
869 goes into 59 0 times with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 93480.0
The remainder is 59 after subtracting 0 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 869, we get 0 and a remainder of 590.
Write down 0 as next digit of the result. 
Result so far: 93480.0
Subtracting 0 from 590 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 10:
5900 divided by 869 is 6 with a remainder of 686.
Use 6 as the next digit of our solution. 
Result so far: 93480.06
If we take 5214 away from 5900, we end up with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 11:
If we divide 6860 by 869, we get 7 and a remainder of 777.
The next digit of our result is 7. 
Result so far: 93480.067
Subtracting 6083 from 6860 leaves us with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

On to step 12:
869 can be fit into 7770 8 times, resulting in a remainder of 818.
Use 8 as the next digit of our solution. 
Result so far: 93480.0678
If we take 6952 away from 7770, we end up with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Moving on to step 13:
8180 divided by 869 is 9 with a remainder of 359.
Put 9 as the next digit of the answer. 
Result so far: 93480.06789
Subtract 7821 from 8180 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 14:
When dividing 3590 by 869, we get 4 with a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 93480.067894
Subtract 3476 from 3590 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 15:
869 can be fit into 1140 1 times, resulting in a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 93480.0678941
If we subtract 869 from 1140, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 16:
869 goes into 2710 3 times with a remainder of 103.
The next digit of our result is 3. 
Result so far: 93480.06789413
Subtracting 2607 from 2710 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Our division results in 93480.06789413 with a remaining 1.03e-07.
