We're dividing 391725 by 55 
Our goal is to divide 391725 by 55.

Moving on to step 1:
The number 55 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 55

Going ahead to step 2:
If we divide 39 by 55, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 55

On to step 3:
When dividing 391 by 55, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 385 from 391, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 55

Moving on to step 4:
67 divided by 55 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 55 from 67, we get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 55

Advancing to step 5:
55 can be fit into 122 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 712.0
Deduct 110 from 122 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 55

Going ahead to step 6:
55 goes into 125 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 7122.0
Deduct 110 from 125 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.

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: 7122.2
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.

On to step 8:
400 divided by 55 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7122.27
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 9:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7122.272
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.

Step 10:
55 goes into 400 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7122.2727
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.

Moving on to step 11:
If we divide 150 by 55, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 7122.27272
Subtract 110 from 150 to get 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 12:
55 can be fit into 400 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 7122.272727
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:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7122.2727272
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.

Moving on to step 14:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 7122.27272727
If we take 385 away from 400, we end up 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 final outcome is 7122.27272727, with a leftover of 1.5e-08.
