35381944 ÷ 151 
The aim is to understand the frequency of 151 in 35381944.

Moving on to step 1:
When dividing 3 by 151, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 151

On to step 2:
If we divide 35 by 151, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 151

Going ahead to step 3:
151 goes into 353 2 times with a remainder of 51.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 51 after subtracting 302 from 353.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 151

Moving on to step 4:
The number 151 fits into 518 3 times, leaving a remainder of 65.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 453 from 518 leaves us with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 151

Let's proceed to step 5:
151 can be fit into 651 4 times, resulting in a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 604 from 651 leaves us with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 151

On to step 6:
151 goes into 479 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 2343.0
If we subtract 453 from 479, we get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 151

Advancing to step 7:
If we divide 264 by 151, we get 1 and a remainder of 113.
The next digit of our result is 1. 
Result so far: 23431.0
If we take 151 away from 264, we end up with 113.
Bring next digit (4) of the dividend behind the 113 and repeat the process: 1134 / 151

Step 8:
151 goes into 1134 7 times with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 234317.0
If we subtract 1057 from 1134, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
If we divide 770 by 151, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 234317.5
Subtracting 755 from 770 leaves us 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.

Moving on to step 10:
If we divide 150 by 151, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 234317.5
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
When dividing 1500 by 151, we get 9 with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 234317.509
The remainder is 141 after subtracting 1359 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 12:
When dividing 1410 by 151, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 234317.5099
If we take 1359 away from 1410, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 234317.5099, with a leftover of 0.00051.
