49738149 ÷ 155 
The aim is to understand the frequency of 155 in 49738149.

Going ahead to step 1:
When dividing 4 by 155, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 155

Going ahead to step 2:
49 divided by 155 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 155

Step 3:
The number 155 fits into 497 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 465 from 497, we get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 155

Advancing to step 4:
When dividing 323 by 155, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 310 from 323, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 155

Going ahead to step 5:
If we divide 138 by 155, we get 0 and a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
The remainder is 138 after subtracting 0 from 138.
Grab the next digit (1) from the dividend, add it to 138, then carry on: 1381 / 155

Advancing to step 6:
If we divide 1381 by 155, we get 8 and a remainder of 141.
Put 8 as the next digit of the answer. 
Result so far: 3208.0
Subtracting 1240 from 1381 leaves us with 141.
Bring next digit (4) of the dividend behind the 141 and repeat the process: 1414 / 155

On to step 7:
155 goes into 1414 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 32089.0
The remainder is 19 after subtracting 1395 from 1414.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 155

Let's proceed to step 8:
When dividing 199 by 155, we get 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 320891.0
Subtracting 155 from 199 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 155 fits into 440 2 times, leaving a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 320891.2
If we take 310 away from 440, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
When dividing 1300 by 155, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 320891.28
Subtracting 1240 from 1300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
If we divide 600 by 155, we get 3 and a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 320891.283
Subtract 465 from 600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 12:
155 goes into 1350 8 times with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 320891.2838
Subtracting 1240 from 1350 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
1100 divided by 155 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 320891.28387
Deduct 1085 from 1100 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.

Let's proceed to step 14:
150 divided by 155 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 320891.28387
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
1500 divided by 155 is 9 with a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 320891.2838709
Subtract 1395 from 1500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 16:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 320891.28387096
Subtracting 930 from 1050 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 320891.28387096 with a remainder of 1.2e-07.
