Let's divide 643639 by 56
We want to divide 643639 by 56.

Advancing to step 1:
When dividing 6 by 56, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 56

Advancing to step 2:
64 divided by 56 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 56 from 64, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 56

Going ahead to step 3:
The number 56 fits into 83 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 56 from 83 to get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 56

Step 4:
If we divide 276 by 56, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 224 away from 276, we end up with 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 56

On to step 5:
When dividing 523 by 56, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 1149.0
If we subtract 504 from 523, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 56

On to step 6:
199 divided by 56 is 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 11493.0
If we subtract 168 from 199, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
56 goes into 310 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11493.5
If we subtract 280 from 310, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 56, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 11493.55
Subtract 280 from 300 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.

Our division results in 11493.55 with a remaining 0.02.
