We're dividing 673986 by 83 
We want to divide 673986 by 83.

On to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 83

Advancing to step 2:
67 divided by 83 is 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 83

Moving on to step 3:
If we divide 673 by 83, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 664 from 673 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 83

Let's proceed to step 4:
When dividing 99 by 83, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 83 from 99, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 83

Let's proceed to step 5:
83 can be fit into 168 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 812.0
Deduct 166 from 168 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 83

Let's proceed to step 6:
83 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 8120.0
Subtract 0 from 26 to get 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 7:
When dividing 260 by 83, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 8120.3
If we take 249 away from 260, we end up with 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 8:
110 divided by 83 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 8120.31
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.

Advancing to step 9:
83 goes into 270 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 8120.313
Deduct 249 from 270 and we're left 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 10:
83 goes into 210 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 8120.3132
Deduct 166 from 210 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
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: 8120.31325
Subtract 415 from 440 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
250 divided by 83 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 8120.313253
Subtracting 249 from 250 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
If we divide 10 by 83, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8120.313253
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
100 divided by 83 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 8120.31325301
Deduct 83 from 100 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 8120.31325301 with a remainder of 1.7e-08.
