4020427 divided by 659 
Our goal is to divide 4020427 by 659.

On to step 1:
The number 659 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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 659

Advancing to step 2:
659 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 659

Advancing to step 3:
402 divided by 659 is 0 with a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 402, we get 402.
Fetch the next digit (0) from the dividend, attach it to 402 and continue: 4020 / 659

Going ahead to step 4:
4020 divided by 659 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3954 from 4020 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 659

Advancing to step 5:
When dividing 664 by 659, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 659 from 664 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 659

Advancing to step 6:
When dividing 52 by 659, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 610.0
If we take 0 away from 52, we end up with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 659

Advancing to step 7:
659 goes into 527 0 times with a remainder of 527.
The next digit of our result is 0. 
Result so far: 6100.0
Subtracting 0 from 527 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Step 8:
659 goes into 5270 7 times with a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 6100.7
If we subtract 4613 from 5270, we get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 9:
When dividing 6570 by 659, we get 9 with a remainder of 639.
The next digit of our result is 9. 
Result so far: 6100.79
Subtracting 5931 from 6570 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 10:
6390 divided by 659 is 9 with a remainder of 459.
Put 9 as the next digit of the answer. 
Result so far: 6100.799
If we subtract 5931 from 6390, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

The final result is 6100.799 with a remainder of 0.0459.
