42750364 divided by 647 
Our goal is to divide 42750364 by 647.

On to step 1:
4 divided by 647 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 647

Advancing to step 2:
647 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 647

On to step 3:
The number 647 fits into 427 0 times, leaving a remainder of 427.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 427 after subtracting 0 from 427.
Take the next digit (5) from the dividend and append it to 427, then repeat: 4275 / 647

Let's proceed to step 4:
647 can be fit into 4275 6 times, resulting in a remainder of 393.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 3882 from 4275, we get 393.
Grab the next digit (0) from the dividend, add it to 393, then carry on: 3930 / 647

Moving on to step 5:
647 can be fit into 3930 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 48 after subtracting 3882 from 3930.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 647

Advancing to step 6:
The number 647 fits into 483 0 times, leaving a remainder of 483.
Write down 0 as next digit of the result. 
Result so far: 660.0
If we subtract 0 from 483, we get 483.
Grab the next digit (6) from the dividend, add it to 483, then carry on: 4836 / 647

On to step 7:
4836 divided by 647 is 7 with a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 6607.0
Subtracting 4529 from 4836 leaves us with 307.
Grab the next digit (4) from the dividend, add it to 307, then carry on: 3074 / 647

On to step 8:
647 can be fit into 3074 4 times, resulting in a remainder of 486.
Record the quotient 4 as the next digit in the result. 
Result so far: 66074.0
Subtract 2588 from 3074 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 9:
4860 divided by 647 is 7 with a remainder of 331.
Record the quotient 7 as the next digit in the result. 
Result so far: 66074.7
Subtract 4529 from 4860 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 10:
The number 647 fits into 3310 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 66074.75
If we subtract 3235 from 3310, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
If we divide 750 by 647, we get 1 and a remainder of 103.
The next digit of our result is 1. 
Result so far: 66074.751
Deduct 647 from 750 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 12:
When dividing 1030 by 647, we get 1 with a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 66074.7511
Subtract 647 from 1030 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

After the division, we end up with 66074.7511 and a remainder of 0.00383.
