We look at the division of 868643 by 83 
We want to figure out the number of times 868643 can be divided by 83.

Let's proceed to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 83

Going ahead to step 2:
83 goes into 86 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 83 away from 86, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 83

Advancing to step 3:
83 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 83

Let's proceed to step 4:
The number 83 fits into 386 4 times, leaving a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 54 after subtracting 332 from 386.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 83

Let's proceed to step 5:
83 can be fit into 544 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 1046.0
The remainder is 46 after subtracting 498 from 544.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 83

Let's proceed to step 6:
463 divided by 83 is 5 with a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 10465.0
Subtract 415 from 463 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
If we divide 480 by 83, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 10465.5
The remainder is 65 after subtracting 415 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
83 can be fit into 650 7 times, resulting in a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 10465.57
Subtracting 581 from 650 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
When dividing 690 by 83, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 10465.578
If we take 664 away from 690, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 83, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 10465.5783
If we subtract 249 from 260, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
83 can be fit into 110 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 10465.57831
Subtracting 83 from 110 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
If we divide 270 by 83, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 10465.578313
If we take 249 away from 270, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
210 divided by 83 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10465.5783132
Subtract 166 from 210 to get 44.
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 83 fits into 440 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10465.57831325
Deduct 415 from 440 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 10465.57831325, and the remainder is 2.5e-08.
