We're dividing 4046120 by 641 
We want to divide 4046120 by 641.

Advancing to step 1:
641 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 641

On to step 2:
40 divided by 641 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 641

Advancing to step 3:
If we divide 404 by 641, we get 0 and a remainder of 404.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 404 and we're left with 404.
Append the next digit (6) from the dividend to 404 and continue with: 4046 / 641

Going ahead to step 4:
When dividing 4046 by 641, we get 6 with a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3846 from 4046 leaves us with 200.
Append the next digit (1) from the dividend to 200 and continue with: 2001 / 641

Moving on to step 5:
If we divide 2001 by 641, we get 3 and a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 1923 from 2001, we get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 641

On to step 6:
782 divided by 641 is 1 with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 631.0
If we take 641 away from 782, we end up with 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 641

Moving on to step 7:
641 goes into 1410 2 times with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 6312.0
If we subtract 1282 from 1410, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 8:
641 goes into 1280 1 times with a remainder of 639.
Put 1 as the next digit of the answer. 
Result so far: 6312.1
If we take 641 away from 1280, we end up 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.

Going ahead to step 9:
641 can be fit into 6390 9 times, resulting in a remainder of 621.
Record the quotient 9 as the next digit in the result. 
Result so far: 6312.19
The remainder is 621 after subtracting 5769 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Advancing to step 10:
When dividing 6210 by 641, we get 9 with a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 6312.199
If we subtract 5769 from 6210, we get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

The quotient of the division is 6312.199, and the remainder is 0.0441.
