We look at the division of 42386141 by 647 
We want to divide 42386141 by 647.

On to step 1:
The number 647 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 647

Moving on to step 2:
647 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 647

Going ahead to step 3:
423 divided by 647 is 0 with a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Include the next digit (8) from the dividend after 423, then repeat: 4238 / 647

On to step 4:
When dividing 4238 by 647, we get 6 with a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3882 from 4238, we get 356.
Fetch the next digit (6) from the dividend, attach it to 356 and continue: 3566 / 647

Moving on to step 5:
647 goes into 3566 5 times with a remainder of 331.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 3235 from 3566 and we're left with 331.
Take the next digit (1) from the dividend and append it to 331, then repeat: 3311 / 647

Going ahead to step 6:
If we divide 3311 by 647, we get 5 and a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 655.0
The remainder is 76 after subtracting 3235 from 3311.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 647

On to step 7:
764 divided by 647 is 1 with a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 6551.0
If we take 647 away from 764, we end up with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 647

Step 8:
647 can be fit into 1171 1 times, resulting in a remainder of 524.
Record the quotient 1 as the next digit in the result. 
Result so far: 65511.0
Subtract 647 from 1171 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 9:
647 can be fit into 5240 8 times, resulting in a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 65511.8
Subtracting 5176 from 5240 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
The number 647 fits into 640 0 times, leaving a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 65511.8
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 11:
If we divide 6400 by 647, we get 9 and a remainder of 577.
Put 9 as the next digit of the answer. 
Result so far: 65511.809
Subtract 5823 from 6400 to get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 12:
647 can be fit into 5770 8 times, resulting in a remainder of 594.
The next digit of our result is 8. 
Result so far: 65511.8098
Subtract 5176 from 5770 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 13:
The number 647 fits into 5940 9 times, leaving a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 65511.80989
The remainder is 117 after subtracting 5823 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 14:
The number 647 fits into 1170 1 times, leaving a remainder of 523.
Write down 1 as next digit of the result. 
Result so far: 65511.809891
Subtract 647 from 1170 to get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 15:
5230 divided by 647 is 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 65511.8098918
Deduct 5176 from 5230 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
540 divided by 647 is 0 with a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 65511.8098918
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 65511.8098918, and the remainder is 5.4e-07.
