Let's divide 645940 by 55
Let's see how many times 55 fits into 645940.

Advancing to step 1:
The number 55 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 55

Moving on to step 2:
If we divide 64 by 55, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 55 away from 64, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 55

Advancing to step 3:
If we divide 95 by 55, we get 1 and a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 55 from 95, we get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 55

Step 4:
409 divided by 55 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 385 from 409 leaves us with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 55

Step 5:
The number 55 fits into 244 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1174.0
Subtracting 220 from 244 leaves us with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 55

Let's proceed to step 6:
The number 55 fits into 240 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 11744.0
Subtracting 220 from 240 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.

Advancing to step 7:
55 goes into 200 3 times with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 11744.3
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 55, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 11744.36
Deduct 330 from 350 and we're left 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.

Going ahead to step 9:
If we divide 200 by 55, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 11744.363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 11744.3636
If we take 330 away from 350, we end up 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.

Advancing to step 11:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 11744.36363
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
55 can be fit into 350 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 11744.363636
Subtracting 330 from 350 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.

Advancing to step 13:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 11744.3636363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 55, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 11744.36363636
If we take 330 away from 350, we end up 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.

The final result is 11744.36363636 with a remainder of 2e-08.
