399111 ÷ 55 
We want to figure out the number of times 399111 can be divided by 55.

Step 1:
55 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 55

Going ahead to step 2:
55 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 55

Step 3:
When dividing 399 by 55, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 385 from 399, we get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 55

On to step 4:
55 can be fit into 141 2 times, resulting in a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 110 from 141 to get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 55

Going ahead to step 5:
When dividing 311 by 55, we get 5 with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 725.0
If we take 275 away from 311, we end up with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 55

Step 6:
When dividing 361 by 55, we get 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 7256.0
The remainder is 31 after subtracting 330 from 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 55 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7256.5
Subtract 275 from 310 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
If we divide 350 by 55, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 7256.56
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 55, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 7256.563
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.

Advancing to step 10:
350 divided by 55 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7256.5636
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.

Step 11:
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: 7256.56363
If we subtract 165 from 200, we get 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 12:
If we divide 350 by 55, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7256.563636
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 13:
55 goes into 200 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 7256.5636363
Subtract 165 from 200 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
If we divide 350 by 55, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 7256.56363636
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.

Our division results in 7256.56363636 with a remaining 2e-08.
