We're dividing 861311 by 84 
We want to figure out the number of times 861311 can be divided by 84.

Let's proceed to step 1:
84 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 84

Step 2:
84 goes into 86 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 84 from 86 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 84

On to step 3:
When dividing 21 by 84, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 84

Let's proceed to step 4:
84 goes into 213 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 45 after subtracting 168 from 213.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 84

Step 5:
When dividing 451 by 84, we get 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 1025.0
Deduct 420 from 451 and we're left with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 84

On to step 6:
311 divided by 84 is 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 10253.0
Deduct 252 from 311 and we're left with 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 7:
84 goes into 590 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 10253.7
Deduct 588 from 590 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 84 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10253.7
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
84 goes into 200 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10253.702
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 10253.7023
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
If we divide 680 by 84, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 10253.70238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 10253.70238
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
When dividing 800 by 84, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 10253.7023809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 10253.70238095
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 10253.70238095 with a remainder of 2e-08.
