64725274 ÷ 646 
We're looking to find how many times 646 goes into 64725274.

Moving on to step 1:
6 divided by 646 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 646

Moving on to step 2:
646 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 646

Going ahead to step 3:
When dividing 647 by 646, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 646 from 647 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 646

Advancing to step 4:
The number 646 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 646

Step 5:
646 goes into 125 0 times with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 125 after subtracting 0 from 125.
Fetch the next digit (2) from the dividend, attach it to 125 and continue: 1252 / 646

Let's proceed to step 6:
When dividing 1252 by 646, we get 1 with a remainder of 606.
Write down 1 as next digit of the result. 
Result so far: 1001.0
Deduct 646 from 1252 and we're left with 606.
Take the next digit (7) from the dividend and append it to 606, then repeat: 6067 / 646

Step 7:
When dividing 6067 by 646, we get 9 with a remainder of 253.
Record the quotient 9 as the next digit in the result. 
Result so far: 10019.0
The remainder is 253 after subtracting 5814 from 6067.
Include the next digit (4) from the dividend after 253, then repeat: 2534 / 646

On to step 8:
The number 646 fits into 2534 3 times, leaving a remainder of 596.
Use 3 as the next digit of our solution. 
Result so far: 100193.0
If we subtract 1938 from 2534, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 9:
646 can be fit into 5960 9 times, resulting in a remainder of 146.
The next digit of our result is 9. 
Result so far: 100193.9
If we take 5814 away from 5960, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 10:
646 can be fit into 1460 2 times, resulting in a remainder of 168.
The next digit of our result is 2. 
Result so far: 100193.92
Deduct 1292 from 1460 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
646 can be fit into 1680 2 times, resulting in a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 100193.922
If we subtract 1292 from 1680, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 100193.922 with a remaining 0.0388.
