We look at the division of 54253443 by 155 
We want to divide 54253443 by 155.

Advancing to step 1:
The number 155 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 155

Let's proceed to step 2:
155 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 155

Step 3:
155 goes into 542 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 465 from 542 leaves us with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 155

Advancing to step 4:
775 divided by 155 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 0 after subtracting 775 from 775.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 155

Let's proceed to step 5:
The number 155 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 350.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 155

Let's proceed to step 6:
When dividing 34 by 155, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 3500.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 155

On to step 7:
If we divide 344 by 155, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 35002.0
Deduct 310 from 344 and we're left with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 155

Advancing to step 8:
If we divide 343 by 155, we get 2 and a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 350022.0
The remainder is 33 after subtracting 310 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
If we divide 330 by 155, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 350022.2
Subtract 310 from 330 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.

Let's proceed to step 10:
The number 155 fits into 200 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 350022.21
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 11:
If we divide 450 by 155, we get 2 and a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 350022.212
If we subtract 310 from 450, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
The number 155 fits into 1400 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 350022.2129
If we take 1395 away from 1400, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
155 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 350022.2129
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.

Advancing to step 14:
When dividing 500 by 155, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 350022.212903
Deduct 465 from 500 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.

On to step 15:
155 goes into 350 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 350022.2129032
The remainder is 40 after subtracting 310 from 350.
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 16:
The number 155 fits into 400 2 times, leaving a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 350022.21290322
Subtracting 310 from 400 leaves us with 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 final result is 350022.21290322 with a remainder of 9e-08.
