426668 ÷ 83 
Our goal is to divide 426668 by 83.

Step 1:
The number 83 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 83

On to step 2:
The number 83 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 83

Going ahead to step 3:
83 goes into 426 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 415 from 426, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 83

Going ahead to step 4:
116 divided by 83 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 83 from 116, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 83

Let's proceed to step 5:
The number 83 fits into 336 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 514.0
Subtracting 332 from 336 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 83

Going ahead to step 6:
83 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 5140.0
If we take 0 away from 48, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
83 can be fit into 480 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5140.5
Subtract 415 from 480 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
If we divide 650 by 83, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 5140.57
If we take 581 away from 650, we end up 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.

Step 9:
690 divided by 83 is 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 5140.578
Subtracting 664 from 690 leaves us 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.

Going ahead to step 10:
If we divide 260 by 83, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 5140.5783
The remainder is 11 after subtracting 249 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 83, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 5140.57831
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:
The number 83 fits into 270 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 5140.578313
Subtract 249 from 270 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
If we divide 210 by 83, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 5140.5783132
If we subtract 166 from 210, we 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.

On to step 14:
440 divided by 83 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5140.57831325
If we take 415 away from 440, we end up 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 final outcome is 5140.57831325, with a leftover of 2.5e-08.
