We divide 640937 by 55
We're looking to find how many times 55 goes into 640937.

Let's proceed to step 1:
55 can be fit into 6 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 55

Step 2:
64 divided by 55 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 55 from 64, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 55

On to step 3:
If we divide 90 by 55, we get 1 and a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 55 from 90 and we're left with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 55

Going ahead to step 4:
If we divide 359 by 55, we get 6 and a remainder of 29.
The next digit of our result is 6. 
Result so far: 116.0
The remainder is 29 after subtracting 330 from 359.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 55

On to step 5:
293 divided by 55 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 1165.0
If we subtract 275 from 293, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 55

Moving on to step 6:
If we divide 187 by 55, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 11653.0
If we subtract 165 from 187, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 55 fits into 220 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 11653.4
The remainder is 0 after subtracting 220 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
55 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11653.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 55 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11653.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11653.4, with a leftover of 0.0.
