We're dividing 66025328 by 463 
The aim is to understand the frequency of 463 in 66025328.

On to step 1:
When dividing 6 by 463, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 463

On to step 2:
If we divide 66 by 463, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 463

Going ahead to step 3:
463 goes into 660 1 times with a remainder of 197.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 463 away from 660, we end up with 197.
Bring next digit (2) of the dividend behind the 197 and repeat the process: 1972 / 463

On to step 4:
463 can be fit into 1972 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 1852 from 1972 and we're left with 120.
Fetch the next digit (5) from the dividend, attach it to 120 and continue: 1205 / 463

Advancing to step 5:
If we divide 1205 by 463, we get 2 and a remainder of 279.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtracting 926 from 1205 leaves us with 279.
Take the next digit (3) from the dividend and append it to 279, then repeat: 2793 / 463

Advancing to step 6:
2793 divided by 463 is 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
Deduct 2778 from 2793 and we're left with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 463

On to step 7:
The number 463 fits into 152 0 times, leaving a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 14260.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 463

Let's proceed to step 8:
When dividing 1528 by 463, we get 3 with a remainder of 139.
Write down 3 as next digit of the result. 
Result so far: 142603.0
Subtract 1389 from 1528 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
463 can be fit into 1390 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 142603.3
If we subtract 1389 from 1390, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 463 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 142603.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 463 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 142603.3
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 142603.3 with a remaining 0.01.
