We look at the division of 155255 by 7 
We want to divide 155255 by 7.

Advancing to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

On to step 2:
If we divide 15 by 7, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 14 from 15, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

Moving on to step 3:
The number 7 fits into 15 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 14 from 15 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Step 4:
The number 7 fits into 12 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtracting 7 from 12 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 7

Advancing to step 5:
55 divided by 7 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 2217.0
Deduct 49 from 55 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 7

Moving on to step 6:
65 divided by 7 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 22179.0
If we take 63 away from 65, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 22179.2
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 22179.28
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 22179.285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 22179.2857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 22179.28571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 22179.285714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 22179.2857142
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 22179.28571428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 22179.28571428, and the remainder is 4e-09.
