643279 divided by 55 
We're looking to find how many times 55 goes into 643279.

On to step 1:
55 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 55

On to step 2:
If we divide 64 by 55, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 55 from 64 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 55

Going ahead to step 3:
55 can be fit into 93 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 55 from 93 and we're left with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 55

On to step 4:
55 goes into 382 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtract 330 from 382 to get 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 55

Going ahead to step 5:
55 can be fit into 527 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 1169.0
If we subtract 495 from 527, we get 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 55

Step 6:
If we divide 329 by 55, we get 5 and a remainder of 54.
The next digit of our result is 5. 
Result so far: 11695.0
Subtracting 275 from 329 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
540 divided by 55 is 9 with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 11695.9
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
When dividing 450 by 55, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 11695.98
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 11695.981
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
55 goes into 450 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 11695.9818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 11695.98181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 11695.981818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
When dividing 100 by 55, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 11695.9818181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 11695.98181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 11695.98181818 with a balance of 1e-08.
