7947231 divided by 551 
The aim is to understand the frequency of 551 in 7947231.

Step 1:
When dividing 7 by 551, we get 0 with 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.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 551

Moving on to step 2:
When dividing 79 by 551, we get 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 551

Step 3:
551 can be fit into 794 1 times, resulting in a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 551 from 794 to get 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 551

Let's proceed to step 4:
551 can be fit into 2437 4 times, resulting in a remainder of 233.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2204 from 2437 leaves us with 233.
Append the next digit (2) from the dividend to 233 and continue with: 2332 / 551

Let's proceed to step 5:
551 goes into 2332 4 times with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtracting 2204 from 2332 leaves us with 128.
Bring next digit (3) of the dividend behind the 128 and repeat the process: 1283 / 551

Advancing to step 6:
551 goes into 1283 2 times with a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 1442.0
Deduct 1102 from 1283 and we're left with 181.
Fetch the next digit (1) from the dividend, attach it to 181 and continue: 1811 / 551

Step 7:
551 goes into 1811 3 times with a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 14423.0
Deduct 1653 from 1811 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 8:
The number 551 fits into 1580 2 times, leaving a remainder of 478.
Record the quotient 2 as the next digit in the result. 
Result so far: 14423.2
Deduct 1102 from 1580 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 9:
551 can be fit into 4780 8 times, resulting in a remainder of 372.
Put 8 as the next digit of the answer. 
Result so far: 14423.28
The remainder is 372 after subtracting 4408 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 10:
3720 divided by 551 is 6 with a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 14423.286
Subtract 3306 from 3720 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 11:
The number 551 fits into 4140 7 times, leaving a remainder of 283.
Record the quotient 7 as the next digit in the result. 
Result so far: 14423.2867
If we subtract 3857 from 4140, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 12:
If we divide 2830 by 551, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 14423.28675
Deduct 2755 from 2830 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
750 divided by 551 is 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 14423.286751
Deduct 551 from 750 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 14:
The number 551 fits into 1990 3 times, leaving a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 14423.2867513
If we subtract 1653 from 1990, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 15:
551 goes into 3370 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 14423.28675136
Subtract 3306 from 3370 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 14423.28675136 with a remaining 6.4e-08.
