Let's divide 52644981 by 903
The aim is to understand the frequency of 903 in 52644981.

On to step 1:
When dividing 5 by 903, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 903

Let's proceed to step 2:
The number 903 fits into 52 0 times, leaving a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 903

Advancing to step 3:
903 can be fit into 526 0 times, resulting in a remainder of 526.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 526, we end up with 526.
Grab the next digit (4) from the dividend, add it to 526, then carry on: 5264 / 903

Moving on to step 4:
When dividing 5264 by 903, we get 5 with a remainder of 749.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4515 from 5264 to get 749.
Append the next digit (4) from the dividend to 749 and continue with: 7494 / 903

Step 5:
The number 903 fits into 7494 8 times, leaving a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 7224 from 7494 to get 270.
Append the next digit (9) from the dividend to 270 and continue with: 2709 / 903

Advancing to step 6:
903 can be fit into 2709 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 583.0
The remainder is 0 after subtracting 2709 from 2709.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 903

Step 7:
903 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 5830.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 903

On to step 8:
903 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 58300.0
Subtract 0 from 81 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
If we divide 810 by 903, we get 0 and a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 58300.0
Subtract 0 from 810 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 10:
903 goes into 8100 8 times with a remainder of 876.
Put 8 as the next digit of the answer. 
Result so far: 58300.08
Deduct 7224 from 8100 and we're left with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Advancing to step 11:
903 goes into 8760 9 times with a remainder of 633.
Record the quotient 9 as the next digit in the result. 
Result so far: 58300.089
The remainder is 633 after subtracting 8127 from 8760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 12:
The number 903 fits into 6330 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 58300.0897
If we subtract 6321 from 6330, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
903 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 58300.0897
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
903 goes into 900 0 times with a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 58300.0897
If we take 0 away from 900, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Our division results in 58300.0897 with a remaining 9e-05.
