We're dividing 83505921 by 861 
We're looking to find how many times 861 goes into 83505921.

On to step 1:
861 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 861

Step 2:
83 divided by 861 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 861

Going ahead to step 3:
835 divided by 861 is 0 with a remainder of 835.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 835 leaves us with 835.
Grab the next digit (0) from the dividend, add it to 835, then carry on: 8350 / 861

Let's proceed to step 4:
When dividing 8350 by 861, we get 9 with a remainder of 601.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7749 from 8350, we get 601.
Fetch the next digit (5) from the dividend, attach it to 601 and continue: 6015 / 861

Advancing to step 5:
6015 divided by 861 is 6 with a remainder of 849.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 849 after subtracting 5166 from 6015.
Include the next digit (9) from the dividend after 849, then repeat: 8499 / 861

Step 6:
The number 861 fits into 8499 9 times, leaving a remainder of 750.
Use 9 as the next digit of our solution. 
Result so far: 969.0
If we subtract 7749 from 8499, we get 750.
Grab the next digit (2) from the dividend, add it to 750, then carry on: 7502 / 861

Advancing to step 7:
861 can be fit into 7502 8 times, resulting in a remainder of 614.
Put 8 as the next digit of the answer. 
Result so far: 9698.0
The remainder is 614 after subtracting 6888 from 7502.
Append the next digit (1) from the dividend to 614 and continue with: 6141 / 861

On to step 8:
The number 861 fits into 6141 7 times, leaving a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 96987.0
Subtract 6027 from 6141 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.

Moving on to step 9:
861 goes into 1140 1 times with a remainder of 279.
Record the quotient 1 as the next digit in the result. 
Result so far: 96987.1
If we subtract 861 from 1140, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 10:
2790 divided by 861 is 3 with a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 96987.13
If we take 2583 away from 2790, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 11:
When dividing 2070 by 861, we get 2 with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 96987.132
The remainder is 348 after subtracting 1722 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 12:
If we divide 3480 by 861, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 96987.1324
Deduct 3444 from 3480 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 861, we get 0 and a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 96987.1324
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 14:
3600 divided by 861 is 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 96987.132404
Subtract 3444 from 3600 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 15:
861 goes into 1560 1 times with a remainder of 699.
Use 1 as the next digit of our solution. 
Result so far: 96987.1324041
The remainder is 699 after subtracting 861 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Step 16:
861 goes into 6990 8 times with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 96987.13240418
If we subtract 6888 from 6990, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

In conclusion, the division gives 96987.13240418 with a balance of 1.02e-07.
