We look at the division of 74547145 by 553 
The aim is to understand the frequency of 553 in 74547145.

Going ahead to step 1:
If we divide 7 by 553, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 553

Going ahead to step 2:
553 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 553

Let's proceed to step 3:
745 divided by 553 is 1 with a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 553 from 745 to get 192.
Fetch the next digit (4) from the dividend, attach it to 192 and continue: 1924 / 553

On to step 4:
If we divide 1924 by 553, we get 3 and a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1659 from 1924, we get 265.
Append the next digit (7) from the dividend to 265 and continue with: 2657 / 553

Going ahead to step 5:
When dividing 2657 by 553, we get 4 with a remainder of 445.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Deduct 2212 from 2657 and we're left with 445.
Include the next digit (1) from the dividend after 445, then repeat: 4451 / 553

On to step 6:
4451 divided by 553 is 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 1348.0
If we subtract 4424 from 4451, we get 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 553

Let's proceed to step 7:
274 divided by 553 is 0 with a remainder of 274.
Put 0 as the next digit of the answer. 
Result so far: 13480.0
If we subtract 0 from 274, we get 274.
Grab the next digit (5) from the dividend, add it to 274, then carry on: 2745 / 553

Advancing to step 8:
553 can be fit into 2745 4 times, resulting in a remainder of 533.
Record the quotient 4 as the next digit in the result. 
Result so far: 134804.0
If we subtract 2212 from 2745, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 9:
When dividing 5330 by 553, we get 9 with a remainder of 353.
The number 9 becomes the next digit in our result. 
Result so far: 134804.9
Subtracting 4977 from 5330 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 10:
When dividing 3530 by 553, we get 6 with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 134804.96
If we take 3318 away from 3530, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
553 goes into 2120 3 times with a remainder of 461.
The next digit of our result is 3. 
Result so far: 134804.963
The remainder is 461 after subtracting 1659 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 12:
The number 553 fits into 4610 8 times, leaving a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 134804.9638
If we take 4424 away from 4610, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 13:
553 goes into 1860 3 times with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 134804.96383
Deduct 1659 from 1860 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 14:
If we divide 2010 by 553, we get 3 and a remainder of 351.
Use 3 as the next digit of our solution. 
Result so far: 134804.963833
Deduct 1659 from 2010 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Our division results in 134804.963833 with a remaining 3.51e-05.
