We look at the division of 70480487 by 274 
The aim is to understand the frequency of 274 in 70480487.

Going ahead to step 1:
The number 274 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 274

Let's proceed to step 2:
When dividing 70 by 274, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 274

Moving on to step 3:
274 goes into 704 2 times with a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 548 from 704, we get 156.
Append the next digit (8) from the dividend to 156 and continue with: 1568 / 274

On to step 4:
When dividing 1568 by 274, we get 5 with a remainder of 198.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 1370 away from 1568, we end up with 198.
Take the next digit (0) from the dividend and append it to 198, then repeat: 1980 / 274

On to step 5:
1980 divided by 274 is 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 257.0
If we take 1918 away from 1980, we end up with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 274

Step 6:
When dividing 624 by 274, we get 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 2572.0
Subtracting 548 from 624 leaves us with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 274

Step 7:
274 goes into 768 2 times with a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 25722.0
Deduct 548 from 768 and we're left with 220.
Grab the next digit (7) from the dividend, add it to 220, then carry on: 2207 / 274

Let's proceed to step 8:
2207 divided by 274 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 257228.0
Subtract 2192 from 2207 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
The number 274 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 257228.0
Deduct 0 from 150 and we're left with 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 10:
The number 274 fits into 1500 5 times, leaving a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 257228.05
Subtract 1370 from 1500 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
1300 divided by 274 is 4 with a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 257228.054
If we subtract 1096 from 1300, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 12:
2040 divided by 274 is 7 with a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 257228.0547
If we subtract 1918 from 2040, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 13:
When dividing 1220 by 274, we get 4 with a remainder of 124.
The next digit of our result is 4. 
Result so far: 257228.05474
If we subtract 1096 from 1220, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
274 can be fit into 1240 4 times, resulting in a remainder of 144.
The next digit of our result is 4. 
Result so far: 257228.054744
Subtract 1096 from 1240 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 257228.054744 with a remainder of 1.44e-05.
