We're dividing 67656581 by 644 
We want to divide 67656581 by 644.

Moving on to step 1:
The number 644 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 644

Advancing to step 2:
644 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 644

On to step 3:
644 goes into 676 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 644 from 676 to get 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 644

Advancing to step 4:
644 goes into 325 0 times with a remainder of 325.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 325 and we're left with 325.
Fetch the next digit (6) from the dividend, attach it to 325 and continue: 3256 / 644

Moving on to step 5:
The number 644 fits into 3256 5 times, leaving a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 3220 away from 3256, we end up with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 644

Going ahead to step 6:
644 goes into 365 0 times with a remainder of 365.
Use 0 as the next digit of our solution. 
Result so far: 1050.0
If we take 0 away from 365, we end up with 365.
Grab the next digit (8) from the dividend, add it to 365, then carry on: 3658 / 644

Step 7:
644 goes into 3658 5 times with a remainder of 438.
Put 5 as the next digit of the answer. 
Result so far: 10505.0
The remainder is 438 after subtracting 3220 from 3658.
Bring next digit (1) of the dividend behind the 438 and repeat the process: 4381 / 644

Step 8:
When dividing 4381 by 644, we get 6 with a remainder of 517.
Put 6 as the next digit of the answer. 
Result so far: 105056.0
If we subtract 3864 from 4381, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 9:
The number 644 fits into 5170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 105056.8
If we take 5152 away from 5170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
The number 644 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 105056.8
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
644 goes into 1800 2 times with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 105056.802
If we take 1288 away from 1800, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 12:
5120 divided by 644 is 7 with a remainder of 612.
Use 7 as the next digit of our solution. 
Result so far: 105056.8027
If we subtract 4508 from 5120, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 13:
644 can be fit into 6120 9 times, resulting in a remainder of 324.
Record the quotient 9 as the next digit in the result. 
Result so far: 105056.80279
If we subtract 5796 from 6120, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 14:
3240 divided by 644 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 105056.802795
Subtracting 3220 from 3240 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
The number 644 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 105056.802795
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 16:
2000 divided by 644 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 105056.80279503
The remainder is 68 after subtracting 1932 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 105056.80279503 with a remainder of 6.8e-08.
