Let's divide 76771830 by 247
The aim is to understand the frequency of 247 in 76771830.

Going ahead to step 1:
247 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 247

Step 2:
When dividing 76 by 247, we get 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 247

Advancing to step 3:
When dividing 767 by 247, we get 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 741 from 767 leaves us with 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 247

On to step 4:
The number 247 fits into 267 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 20 after subtracting 247 from 267.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 247

Step 5:
If we divide 201 by 247, we get 0 and a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 310.0
Subtract 0 from 201 to get 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 247

Going ahead to step 6:
2018 divided by 247 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 3108.0
If we subtract 1976 from 2018, we get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 247

Let's proceed to step 7:
247 goes into 423 1 times with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 31081.0
If we subtract 247 from 423, we get 176.
Fetch the next digit (0) from the dividend, attach it to 176 and continue: 1760 / 247

Let's proceed to step 8:
The number 247 fits into 1760 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 310817.0
The remainder is 31 after subtracting 1729 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
If we divide 310 by 247, we get 1 and a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 310817.1
The remainder is 63 after subtracting 247 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
630 divided by 247 is 2 with a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 310817.12
If we take 494 away from 630, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 11:
1360 divided by 247 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 310817.125
If we subtract 1235 from 1360, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
247 can be fit into 1250 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 310817.1255
If we take 1235 away from 1250, we end up 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.

The final result is 310817.1255 with a remainder of 0.00015.
