We're dividing 643764 by 56 
We want to divide 643764 by 56.

Step 1:
If we divide 6 by 56, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 56

Advancing to step 2:
56 goes into 64 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 56 from 64 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 56

Let's proceed to step 3:
83 divided by 56 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 56 from 83, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 56

Moving on to step 4:
56 goes into 277 4 times with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we subtract 224 from 277, we get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 56

On to step 5:
56 can be fit into 536 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 1149.0
Deduct 504 from 536 and we're left with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 56

Advancing to step 6:
56 goes into 324 5 times with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 11495.0
The remainder is 44 after subtracting 280 from 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 56, we get 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 11495.7
Deduct 392 from 440 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
480 divided by 56 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 11495.78
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 56, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 11495.785
If we take 280 away from 320, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 56 fits into 400 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 11495.7857
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 56, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 11495.78571
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 56 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11495.785714
Deduct 224 from 240 and we're left 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.

Let's proceed to step 13:
If we divide 160 by 56, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 11495.7857142
Subtracting 112 from 160 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 56, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 11495.78571428
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 11495.78571428 and a remainder of 3.2e-08.
