Let's divide 51027234 by 354
The aim is to understand the frequency of 354 in 51027234.

Advancing to step 1:
When dividing 5 by 354, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 354

Moving on to step 2:
51 divided by 354 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 354

On to step 3:
510 divided by 354 is 1 with a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 354 from 510 leaves us with 156.
Append the next digit (2) from the dividend to 156 and continue with: 1562 / 354

Let's proceed to step 4:
1562 divided by 354 is 4 with a remainder of 146.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1416 from 1562 and we're left with 146.
Include the next digit (7) from the dividend after 146, then repeat: 1467 / 354

Going ahead to step 5:
The number 354 fits into 1467 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 1416 from 1467 leaves us with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 354

On to step 6:
354 can be fit into 512 1 times, resulting in a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1441.0
Deduct 354 from 512 and we're left with 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 354

Advancing to step 7:
The number 354 fits into 1583 4 times, leaving a remainder of 167.
Put 4 as the next digit of the answer. 
Result so far: 14414.0
If we subtract 1416 from 1583, we get 167.
Append the next digit (4) from the dividend to 167 and continue with: 1674 / 354

Step 8:
354 can be fit into 1674 4 times, resulting in a remainder of 258.
The number 4 becomes the next digit in our result. 
Result so far: 144144.0
If we subtract 1416 from 1674, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
If we divide 2580 by 354, we get 7 and a remainder of 102.
Record the quotient 7 as the next digit in the result. 
Result so far: 144144.7
Subtract 2478 from 2580 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 10:
If we divide 1020 by 354, we get 2 and a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 144144.72
If we subtract 708 from 1020, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 11:
The number 354 fits into 3120 8 times, leaving a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 144144.728
The remainder is 288 after subtracting 2832 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
354 goes into 2880 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 144144.7288
Subtracting 2832 from 2880 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 144144.7288, with a leftover of 0.00048.
