We're dividing 73580437 by 551 
The aim is to understand the frequency of 551 in 73580437.

Let's proceed to step 1:
The number 551 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 551

Advancing to step 2:
551 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 551

Going ahead to step 3:
When dividing 735 by 551, we get 1 with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 551 from 735 to get 184.
Fetch the next digit (8) from the dividend, attach it to 184 and continue: 1848 / 551

Going ahead to step 4:
The number 551 fits into 1848 3 times, leaving a remainder of 195.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 195 after subtracting 1653 from 1848.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 551

Advancing to step 5:
If we divide 1950 by 551, we get 3 and a remainder of 297.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtracting 1653 from 1950 leaves us with 297.
Bring next digit (4) of the dividend behind the 297 and repeat the process: 2974 / 551

Step 6:
551 can be fit into 2974 5 times, resulting in a remainder of 219.
Use 5 as the next digit of our solution. 
Result so far: 1335.0
The remainder is 219 after subtracting 2755 from 2974.
Fetch the next digit (3) from the dividend, attach it to 219 and continue: 2193 / 551

Advancing to step 7:
If we divide 2193 by 551, we get 3 and a remainder of 540.
Record the quotient 3 as the next digit in the result. 
Result so far: 13353.0
Subtracting 1653 from 2193 leaves us with 540.
Include the next digit (7) from the dividend after 540, then repeat: 5407 / 551

Advancing to step 8:
The number 551 fits into 5407 9 times, leaving a remainder of 448.
Use 9 as the next digit of our solution. 
Result so far: 133539.0
Subtracting 4959 from 5407 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
When dividing 4480 by 551, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 133539.8
Subtract 4408 from 4480 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
When dividing 720 by 551, we get 1 with a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 133539.81
If we subtract 551 from 720, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 11:
551 can be fit into 1690 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 133539.813
Subtracting 1653 from 1690 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
551 can be fit into 370 0 times, resulting in a remainder of 370.
The next digit of our result is 0. 
Result so far: 133539.813
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 13:
If we divide 3700 by 551, we get 6 and a remainder of 394.
The next digit of our result is 6. 
Result so far: 133539.81306
Subtracting 3306 from 3700 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 14:
3940 divided by 551 is 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 133539.813067
Subtracting 3857 from 3940 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 15:
When dividing 830 by 551, we get 1 with a remainder of 279.
The next digit of our result is 1. 
Result so far: 133539.8130671
Deduct 551 from 830 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 16:
551 goes into 2790 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 133539.81306715
Subtract 2755 from 2790 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 133539.81306715 with a remaining 3.5e-08.
