We divide 53143686 by 155
The aim is to understand the frequency of 155 in 53143686.

On to step 1:
If we divide 5 by 155, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 155

On to step 2:
If we divide 53 by 155, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 155

Advancing to step 3:
The number 155 fits into 531 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 465 away from 531, we end up with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 155

Let's proceed to step 4:
155 goes into 664 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 620 away from 664, we end up with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 155

On to step 5:
When dividing 443 by 155, we get 2 with a remainder of 133.
Use 2 as the next digit of our solution. 
Result so far: 342.0
The remainder is 133 after subtracting 310 from 443.
Include the next digit (6) from the dividend after 133, then repeat: 1336 / 155

Let's proceed to step 6:
1336 divided by 155 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 3428.0
Subtracting 1240 from 1336 leaves us with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 155

Let's proceed to step 7:
968 divided by 155 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 34286.0
If we subtract 930 from 968, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 155

On to step 8:
155 can be fit into 386 2 times, resulting in a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 342862.0
If we subtract 310 from 386, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
155 can be fit into 760 4 times, resulting in a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 342862.4
If we take 620 away from 760, 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.

Going ahead to step 10:
1400 divided by 155 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 342862.49
Deduct 1395 from 1400 and we're left 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.

Step 11:
When dividing 50 by 155, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 342862.49
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 155 fits into 500 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 342862.4903
Subtract 465 from 500 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
If we divide 350 by 155, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 342862.49032
If we subtract 310 from 350, we 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.

Going ahead to step 14:
155 can be fit into 400 2 times, resulting in a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 342862.490322
If we subtract 310 from 400, we 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 342862.490322, and the remainder is 9e-06.
