Let's divide 72477773 by 551
The aim is to understand the frequency of 551 in 72477773.

Step 1:
When dividing 7 by 551, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 551

Moving on to step 2:
72 divided by 551 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 551

Advancing to step 3:
551 goes into 724 1 times with a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 551 away from 724, we end up with 173.
Take the next digit (7) from the dividend and append it to 173, then repeat: 1737 / 551

Advancing to step 4:
When dividing 1737 by 551, we get 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1653 from 1737 to get 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 551

Advancing to step 5:
If we divide 847 by 551, we get 1 and a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Deduct 551 from 847 and we're left with 296.
Take the next digit (7) from the dividend and append it to 296, then repeat: 2967 / 551

Moving on to step 6:
2967 divided by 551 is 5 with a remainder of 212.
The number 5 becomes the next digit in our result. 
Result so far: 1315.0
Subtract 2755 from 2967 to get 212.
Grab the next digit (7) from the dividend, add it to 212, then carry on: 2127 / 551

Step 7:
551 goes into 2127 3 times with a remainder of 474.
Record the quotient 3 as the next digit in the result. 
Result so far: 13153.0
If we take 1653 away from 2127, we end up with 474.
Take the next digit (3) from the dividend and append it to 474, then repeat: 4743 / 551

Advancing to step 8:
When dividing 4743 by 551, we get 8 with a remainder of 335.
Write down 8 as next digit of the result. 
Result so far: 131538.0
Subtracting 4408 from 4743 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
If we divide 3350 by 551, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 131538.6
The remainder is 44 after subtracting 3306 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 551, we get 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 131538.6
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
The number 551 fits into 4400 7 times, leaving a remainder of 543.
The next digit of our result is 7. 
Result so far: 131538.607
The remainder is 543 after subtracting 3857 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 12:
551 can be fit into 5430 9 times, resulting in a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 131538.6079
If we take 4959 away from 5430, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 13:
The number 551 fits into 4710 8 times, leaving a remainder of 302.
Put 8 as the next digit of the answer. 
Result so far: 131538.60798
The remainder is 302 after subtracting 4408 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 14:
551 can be fit into 3020 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 131538.607985
The remainder is 265 after subtracting 2755 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 15:
The number 551 fits into 2650 4 times, leaving a remainder of 446.
Use 4 as the next digit of our solution. 
Result so far: 131538.6079854
Deduct 2204 from 2650 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 16:
When dividing 4460 by 551, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 131538.60798548
Subtract 4408 from 4460 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 131538.60798548 with a remaining 5.2e-08.
