426245 ÷ 86 
We're looking to find how many times 86 goes into 426245.

Advancing to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 86

On to step 2:
When dividing 42 by 86, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 86

On to step 3:
426 divided by 86 is 4 with a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 344 from 426 leaves us with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 86

Advancing to step 4:
86 goes into 822 9 times with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 774 from 822 leaves us with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 86

On to step 5:
86 goes into 484 5 times with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 495.0
If we subtract 430 from 484, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 86

Advancing to step 6:
The number 86 fits into 545 6 times, leaving a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 4956.0
Deduct 516 from 545 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
If we divide 290 by 86, we get 3 and a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 4956.3
Subtracting 258 from 290 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
86 goes into 320 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4956.33
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 4956.33 with a remainder of 0.062.
