We're dividing 49937941 by 149 
The aim is to understand the frequency of 149 in 49937941.

On to step 1:
4 divided by 149 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 149

Advancing to step 2:
The number 149 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 149

Advancing to step 3:
If we divide 499 by 149, we get 3 and a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 447 from 499 and we're left with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 149

Step 4:
If we divide 523 by 149, we get 3 and a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 447 from 523 leaves us with 76.
Grab the next digit (7) from the dividend, add it to 76, then carry on: 767 / 149

Going ahead to step 5:
149 goes into 767 5 times with a remainder of 22.
The next digit of our result is 5. 
Result so far: 335.0
Subtracting 745 from 767 leaves us with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 149

Step 6:
229 divided by 149 is 1 with a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 3351.0
If we subtract 149 from 229, we get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 149

Step 7:
If we divide 804 by 149, we get 5 and a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 33515.0
If we take 745 away from 804, we end up with 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 149

Going ahead to step 8:
When dividing 591 by 149, we get 3 with a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 335153.0
Subtracting 447 from 591 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
When dividing 1440 by 149, we get 9 with a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 335153.9
If we take 1341 away from 1440, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 10:
149 goes into 990 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 335153.96
Deduct 894 from 990 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
The number 149 fits into 960 6 times, leaving a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 335153.966
If we take 894 away from 960, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 335153.966 with a remainder of 0.0066.
