We look at the division of 5257509 by 155 
We want to divide 5257509 by 155.

Moving on to step 1:
5 divided by 155 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 155

Step 2:
155 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 155

Step 3:
If we divide 525 by 155, we get 3 and a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 60 after subtracting 465 from 525.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 155

Going ahead to step 4:
155 can be fit into 607 3 times, resulting in a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 142 after subtracting 465 from 607.
Fetch the next digit (5) from the dividend, attach it to 142 and continue: 1425 / 155

On to step 5:
155 goes into 1425 9 times with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 339.0
Subtract 1395 from 1425 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 155

Advancing to step 6:
155 goes into 300 1 times with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 3391.0
The remainder is 145 after subtracting 155 from 300.
Fetch the next digit (9) from the dividend, attach it to 145 and continue: 1459 / 155

On to step 7:
1459 divided by 155 is 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 33919.0
The remainder is 64 after subtracting 1395 from 1459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
The number 155 fits into 640 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 33919.4
If we take 620 away from 640, 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 9:
If we divide 200 by 155, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 33919.41
Subtract 155 from 200 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.

Step 10:
The number 155 fits into 450 2 times, leaving a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 33919.412
If we take 310 away from 450, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 155, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 33919.4129
If we subtract 1395 from 1400, 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.

Step 12:
155 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 33919.4129
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
155 can be fit into 500 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 33919.412903
The remainder is 35 after subtracting 465 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
155 can be fit into 350 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 33919.4129032
Deduct 310 from 350 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 15:
155 can be fit into 400 2 times, resulting in a remainder of 90.
The next digit of our result is 2. 
Result so far: 33919.41290322
Subtract 310 from 400 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The quotient of the division is 33919.41290322, and the remainder is 9e-08.
