We divide 86120248 by 869
We want to divide 86120248 by 869.

Let's proceed to step 1:
869 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 869

Advancing to step 2:
The number 869 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 869

Let's proceed to step 3:
If we divide 861 by 869, we get 0 and a remainder of 861.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 861, we get 861.
Fetch the next digit (2) from the dividend, attach it to 861 and continue: 8612 / 869

Going ahead to step 4:
8612 divided by 869 is 9 with a remainder of 791.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7821 from 8612, we get 791.
Take the next digit (0) from the dividend and append it to 791, then repeat: 7910 / 869

Going ahead to step 5:
When dividing 7910 by 869, we get 9 with a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 7821 from 7910 leaves us with 89.
Bring next digit (2) of the dividend behind the 89 and repeat the process: 892 / 869

Going ahead to step 6:
The number 869 fits into 892 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 991.0
Subtracting 869 from 892 leaves us with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 869

On to step 7:
When dividing 234 by 869, we get 0 with a remainder of 234.
The number 0 becomes the next digit in our result. 
Result so far: 9910.0
If we take 0 away from 234, we end up with 234.
Grab the next digit (8) from the dividend, add it to 234, then carry on: 2348 / 869

Moving on to step 8:
869 goes into 2348 2 times with a remainder of 610.
Put 2 as the next digit of the answer. 
Result so far: 99102.0
Subtract 1738 from 2348 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 9:
869 can be fit into 6100 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 99102.7
If we subtract 6083 from 6100, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
When dividing 170 by 869, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 99102.7
If we take 0 away from 170, 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.

Let's proceed to step 11:
The number 869 fits into 1700 1 times, leaving a remainder of 831.
Put 1 as the next digit of the answer. 
Result so far: 99102.701
If we subtract 869 from 1700, we get 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Moving on to step 12:
If we divide 8310 by 869, we get 9 and a remainder of 489.
Write down 9 as next digit of the result. 
Result so far: 99102.7019
Subtracting 7821 from 8310 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 13:
The number 869 fits into 4890 5 times, leaving a remainder of 545.
Use 5 as the next digit of our solution. 
Result so far: 99102.70195
Subtract 4345 from 4890 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 14:
869 can be fit into 5450 6 times, resulting in a remainder of 236.
Write down 6 as next digit of the result. 
Result so far: 99102.701956
The remainder is 236 after subtracting 5214 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 15:
The number 869 fits into 2360 2 times, leaving a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 99102.7019562
Subtract 1738 from 2360 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 16:
6220 divided by 869 is 7 with a remainder of 137.
Put 7 as the next digit of the answer. 
Result so far: 99102.70195627
If we take 6083 away from 6220, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 99102.70195627, with a leftover of 1.37e-07.
