We look at the division of 399169 by 55 
We want to divide 399169 by 55.

Going ahead to step 1:
When dividing 3 by 55, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 55

Let's proceed to step 2:
If we divide 39 by 55, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 55

Let's proceed to step 3:
399 divided by 55 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 14 after subtracting 385 from 399.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 55

Let's proceed to step 4:
141 divided by 55 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 110 from 141 and we're left with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 55

Advancing to step 5:
When dividing 316 by 55, we get 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 725.0
Subtracting 275 from 316 leaves us with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 55

Moving on to step 6:
If we divide 419 by 55, we get 7 and a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 7257.0
If we take 385 away from 419, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 55, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 7257.6
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
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: 7257.61
Subtract 55 from 100 to 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 9:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 7257.618
Subtracting 440 from 450 leaves us with 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 10:
When dividing 100 by 55, we get 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 7257.6181
Subtract 55 from 100 to 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.

Let's proceed to step 11:
55 goes into 450 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 7257.61818
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 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 7257.618181
If we take 55 away from 100, we end up 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.

Let's proceed to step 13:
When dividing 450 by 55, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 7257.6181818
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.

Step 14:
The number 55 fits into 100 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 7257.61818181
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.

Our division results in 7257.61818181 with a remaining 4.5e-08.
