We look at the division of 37899901 by 48 
The aim is to understand the frequency of 48 in 37899901.

Let's proceed to step 1:
The number 48 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 48

Step 2:
When dividing 37 by 48, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 48

On to step 3:
48 can be fit into 378 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 336 from 378 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 48

Step 4:
429 divided by 48 is 8 with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 384 from 429 leaves us with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 48

Step 5:
459 divided by 48 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 789.0
Subtract 432 from 459 to get 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 48

Advancing to step 6:
The number 48 fits into 279 5 times, leaving a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 7895.0
Deduct 240 from 279 and we're left with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 48

Going ahead to step 7:
When dividing 390 by 48, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 78958.0
Subtracting 384 from 390 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 48

On to step 8:
When dividing 61 by 48, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 789581.0
If we subtract 48 from 61, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 48, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 789581.2
If we take 96 away from 130, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
48 goes into 340 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 789581.27
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
48 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 789581.27
Subtract 0 from 40 to 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.

Step 12:
400 divided by 48 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 789581.2708
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 48 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 789581.27083
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
160 divided by 48 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 789581.270833
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 789581.270833 with a balance of 1.6e-06.
