We divide 640435 by 55
We want to divide 640435 by 55.

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
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 55

Moving on to step 2:
64 divided by 55 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 55 from 64 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 55

Step 3:
When dividing 90 by 55, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 55 from 90 and we're left with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 55

Step 4:
If we divide 354 by 55, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 330 from 354 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 55

Advancing to step 5:
If we divide 243 by 55, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 1164.0
Subtract 220 from 243 to get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 55

Moving on to step 6:
If we divide 235 by 55, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 11644.0
Subtract 220 from 235 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
55 can be fit into 150 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 11644.2
If we take 110 away from 150, 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.

Going ahead to step 8:
If we divide 400 by 55, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 11644.27
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 55 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 11644.272
Deduct 110 from 150 and we're left 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.

Let's proceed to step 10:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 11644.2727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
When dividing 150 by 55, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 11644.27272
If we take 110 away from 150, 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.

Going ahead to step 12:
55 can be fit into 400 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 11644.272727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
If we divide 150 by 55, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 11644.2727272
If we take 110 away from 150, 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.

Going ahead to step 14:
If we divide 400 by 55, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 11644.27272727
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 11644.27272727, and the remainder is 1.5e-08.
