644646 ÷ 47 
We're looking to find how many times 47 goes into 644646.

Moving on to step 1:
When dividing 6 by 47, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 47

On to step 2:
When dividing 64 by 47, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 47 from 64 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 47

Advancing to step 3:
The number 47 fits into 174 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 141 away from 174, we end up with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 47

Step 4:
When dividing 336 by 47, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtract 329 from 336 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 47

Advancing to step 5:
When dividing 74 by 47, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1371.0
If we take 47 away from 74, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 47

Moving on to step 6:
When dividing 276 by 47, we get 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 13715.0
If we take 235 away from 276, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
The number 47 fits into 410 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 13715.8
If we subtract 376 from 410, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
47 goes into 340 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 13715.87
Subtracting 329 from 340 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 47 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 13715.872
If we take 94 away from 110, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
47 goes into 160 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 13715.8723
Subtract 141 from 160 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
The number 47 fits into 190 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 13715.87234
Subtract 188 from 190 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
If we divide 20 by 47, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13715.87234
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 47, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 13715.8723404
Subtract 188 from 200 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
When dividing 120 by 47, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 13715.87234042
If we subtract 94 from 120, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 13715.87234042 and a remainder of 2.6e-08.
