We look at the division of 49253976 by 157 
The aim is to understand the frequency of 157 in 49253976.

Moving on to step 1:
If we divide 4 by 157, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 157

Moving on to step 2:
When dividing 49 by 157, we get 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 157

Let's proceed to step 3:
If we divide 492 by 157, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 471 away from 492, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 157

On to step 4:
The number 157 fits into 215 1 times, leaving a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 157 from 215, we get 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 157

Going ahead to step 5:
157 can be fit into 583 3 times, resulting in a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtract 471 from 583 to get 112.
Fetch the next digit (9) from the dividend, attach it to 112 and continue: 1129 / 157

Advancing to step 6:
1129 divided by 157 is 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 3137.0
Deduct 1099 from 1129 and we're left with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 157

On to step 7:
When dividing 307 by 157, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 31371.0
Subtracting 157 from 307 leaves us with 150.
Bring next digit (6) of the dividend behind the 150 and repeat the process: 1506 / 157

Step 8:
The number 157 fits into 1506 9 times, leaving a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 313719.0
Deduct 1413 from 1506 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
The number 157 fits into 930 5 times, leaving a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 313719.5
Subtracting 785 from 930 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
When dividing 1450 by 157, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 313719.59
Subtracting 1413 from 1450 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
370 divided by 157 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 313719.592
Subtracting 314 from 370 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
560 divided by 157 is 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 313719.5923
Deduct 471 from 560 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
157 goes into 890 5 times with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 313719.59235
Subtracting 785 from 890 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 14:
If we divide 1050 by 157, we get 6 and a remainder of 108.
The next digit of our result is 6. 
Result so far: 313719.592356
Deduct 942 from 1050 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 15:
The number 157 fits into 1080 6 times, leaving a remainder of 138.
The next digit of our result is 6. 
Result so far: 313719.5923566
If we subtract 942 from 1080, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 313719.5923566 with a remainder of 1.38e-06.
