We look at the division of 51293407 by 247 
The aim is to understand the frequency of 247 in 51293407.

Step 1:
If we divide 5 by 247, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 247

Let's proceed to step 2:
247 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 247

Let's proceed to step 3:
512 divided by 247 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 494 from 512 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 247

Moving on to step 4:
247 can be fit into 189 0 times, resulting in a remainder of 189.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 189, we get 189.
Take the next digit (3) from the dividend and append it to 189, then repeat: 1893 / 247

Going ahead to step 5:
1893 divided by 247 is 7 with a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 207.0
If we take 1729 away from 1893, we end up with 164.
Take the next digit (4) from the dividend and append it to 164, then repeat: 1644 / 247

Step 6:
When dividing 1644 by 247, we get 6 with a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 2076.0
Subtract 1482 from 1644 to get 162.
Include the next digit (0) from the dividend after 162, then repeat: 1620 / 247

Let's proceed to step 7:
If we divide 1620 by 247, we get 6 and a remainder of 138.
The next digit of our result is 6. 
Result so far: 20766.0
If we subtract 1482 from 1620, we get 138.
Take the next digit (7) from the dividend and append it to 138, then repeat: 1387 / 247

Let's proceed to step 8:
When dividing 1387 by 247, we get 5 with a remainder of 152.
The number 5 becomes the next digit in our result. 
Result so far: 207665.0
The remainder is 152 after subtracting 1235 from 1387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 9:
1520 divided by 247 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 207665.6
Subtracting 1482 from 1520 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
When dividing 380 by 247, we get 1 with a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 207665.61
The remainder is 133 after subtracting 247 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 11:
The number 247 fits into 1330 5 times, leaving a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 207665.615
Deduct 1235 from 1330 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
950 divided by 247 is 3 with a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 207665.6153
Subtracting 741 from 950 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 13:
247 can be fit into 2090 8 times, resulting in a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 207665.61538
Deduct 1976 from 2090 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 14:
247 goes into 1140 4 times with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 207665.615384
If we subtract 988 from 1140, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
If we divide 1520 by 247, we get 6 and a remainder of 38.
The next digit of our result is 6. 
Result so far: 207665.6153846
Subtracting 1482 from 1520 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
247 goes into 380 1 times with a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 207665.61538461
Subtract 247 from 380 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The quotient of the division is 207665.61538461, and the remainder is 1.33e-07.
