Let's divide 42068261 by 660
We want to divide 42068261 by 660.

Moving on to step 1:
When dividing 4 by 660, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 660

Let's proceed to step 2:
The number 660 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 660

Moving on to step 3:
If we divide 420 by 660, we get 0 and a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 420 after subtracting 0 from 420.
Bring next digit (6) of the dividend behind the 420 and repeat the process: 4206 / 660

Going ahead to step 4:
The number 660 fits into 4206 6 times, leaving a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 246 after subtracting 3960 from 4206.
Take the next digit (8) from the dividend and append it to 246, then repeat: 2468 / 660

On to step 5:
When dividing 2468 by 660, we get 3 with a remainder of 488.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 1980 away from 2468, we end up with 488.
Bring next digit (2) of the dividend behind the 488 and repeat the process: 4882 / 660

Let's proceed to step 6:
660 can be fit into 4882 7 times, resulting in a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 637.0
If we subtract 4620 from 4882, we get 262.
Append the next digit (6) from the dividend to 262 and continue with: 2626 / 660

On to step 7:
When dividing 2626 by 660, we get 3 with a remainder of 646.
Record the quotient 3 as the next digit in the result. 
Result so far: 6373.0
If we subtract 1980 from 2626, we get 646.
Append the next digit (1) from the dividend to 646 and continue with: 6461 / 660

Let's proceed to step 8:
If we divide 6461 by 660, we get 9 and a remainder of 521.
Use 9 as the next digit of our solution. 
Result so far: 63739.0
Subtract 5940 from 6461 to get 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

On to step 9:
If we divide 5210 by 660, we get 7 and a remainder of 590.
The next digit of our result is 7. 
Result so far: 63739.7
If we take 4620 away from 5210, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 10:
660 can be fit into 5900 8 times, resulting in a remainder of 620.
Use 8 as the next digit of our solution. 
Result so far: 63739.78
The remainder is 620 after subtracting 5280 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 11:
When dividing 6200 by 660, we get 9 with a remainder of 260.
Record the quotient 9 as the next digit in the result. 
Result so far: 63739.789
If we subtract 5940 from 6200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
660 goes into 2600 3 times with a remainder of 620.
The next digit of our result is 3. 
Result so far: 63739.7893
If we subtract 1980 from 2600, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 13:
6200 divided by 660 is 9 with a remainder of 260.
The number 9 becomes the next digit in our result. 
Result so far: 63739.78939
If we take 5940 away from 6200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
660 goes into 2600 3 times with a remainder of 620.
The next digit of our result is 3. 
Result so far: 63739.789393
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 15:
When dividing 6200 by 660, we get 9 with a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 63739.7893939
The remainder is 260 after subtracting 5940 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
When dividing 2600 by 660, we get 3 with a remainder of 620.
Write down 3 as next digit of the result. 
Result so far: 63739.78939393
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

After the division, we end up with 63739.78939393 and a remainder of 6.2e-07.
