We look at the division of 83955921 by 869 
Let's see how many times 869 fits into 83955921.

Let's proceed to step 1:
When dividing 8 by 869, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 869

Step 2:
The number 869 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 869

Moving on to step 3:
If we divide 839 by 869, we get 0 and a remainder of 839.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 839 after subtracting 0 from 839.
Bring next digit (5) of the dividend behind the 839 and repeat the process: 8395 / 869

Going ahead to step 4:
869 can be fit into 8395 9 times, resulting in a remainder of 574.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7821 away from 8395, we end up with 574.
Bring next digit (5) of the dividend behind the 574 and repeat the process: 5745 / 869

Step 5:
869 goes into 5745 6 times with a remainder of 531.
Write down 6 as next digit of the result. 
Result so far: 96.0
Deduct 5214 from 5745 and we're left with 531.
Include the next digit (9) from the dividend after 531, then repeat: 5319 / 869

Going ahead to step 6:
5319 divided by 869 is 6 with a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 966.0
Deduct 5214 from 5319 and we're left with 105.
Take the next digit (2) from the dividend and append it to 105, then repeat: 1052 / 869

Step 7:
869 goes into 1052 1 times with a remainder of 183.
The number 1 becomes the next digit in our result. 
Result so far: 9661.0
Deduct 869 from 1052 and we're left with 183.
Include the next digit (1) from the dividend after 183, then repeat: 1831 / 869

Step 8:
The number 869 fits into 1831 2 times, leaving a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 96612.0
Deduct 1738 from 1831 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
869 can be fit into 930 1 times, resulting in a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 96612.1
Deduct 869 from 930 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
If we divide 610 by 869, we get 0 and a remainder of 610.
The next digit of our result is 0. 
Result so far: 96612.1
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 11:
6100 divided by 869 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 96612.107
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.

On to step 12:
869 can be fit into 170 0 times, resulting in a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 96612.107
Subtracting 0 from 170 leaves us 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 13:
If we divide 1700 by 869, we get 1 and a remainder of 831.
Record the quotient 1 as the next digit in the result. 
Result so far: 96612.10701
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.

Going ahead to step 14:
869 can be fit into 8310 9 times, resulting in a remainder of 489.
Put 9 as the next digit of the answer. 
Result so far: 96612.107019
Subtract 7821 from 8310 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 15:
4890 divided by 869 is 5 with a remainder of 545.
The next digit of our result is 5. 
Result so far: 96612.1070195
Subtracting 4345 from 4890 leaves us with 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 16:
5450 divided by 869 is 6 with a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 96612.10701956
Subtracting 5214 from 5450 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 96612.10701956 with a balance of 2.36e-07.
