We're dividing 646870 by 55 
We're looking to find how many times 55 goes into 646870.

Step 1:
The number 55 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 55

Step 2:
55 can be fit into 64 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 55 from 64 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 55

On to step 3:
55 goes into 96 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 55 from 96 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 55

Moving on to step 4:
When dividing 418 by 55, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 33 after subtracting 385 from 418.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 55

Moving on to step 5:
55 goes into 337 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 1176.0
If we subtract 330 from 337, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 55

On to step 6:
55 goes into 70 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11761.0
If we subtract 55 from 70, we 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.

Moving on to step 7:
When dividing 150 by 55, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 11761.2
Subtracting 110 from 150 leaves us 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.

Advancing to step 8:
When dividing 400 by 55, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 11761.27
If we subtract 385 from 400, we 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 9:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 11761.272
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.

Advancing to step 10:
55 goes into 400 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 11761.2727
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 11:
150 divided by 55 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 11761.27272
The remainder is 40 after subtracting 110 from 150.
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:
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: 11761.272727
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.

Going ahead to step 13:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 11761.2727272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 11761.27272727
Deduct 385 from 400 and we're left 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.

Our division results in 11761.27272727 with a remaining 1.5e-08.
