We're dividing 73966306 by 575 
The aim is to understand the frequency of 575 in 73966306.

Step 1:
575 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 575

On to step 2:
The number 575 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 575

Step 3:
739 divided by 575 is 1 with a remainder of 164.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 575 from 739 to get 164.
Bring next digit (6) of the dividend behind the 164 and repeat the process: 1646 / 575

Step 4:
When dividing 1646 by 575, we get 2 with a remainder of 496.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 496 after subtracting 1150 from 1646.
Append the next digit (6) from the dividend to 496 and continue with: 4966 / 575

On to step 5:
When dividing 4966 by 575, we get 8 with a remainder of 366.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 4600 from 4966 and we're left with 366.
Include the next digit (3) from the dividend after 366, then repeat: 3663 / 575

Let's proceed to step 6:
3663 divided by 575 is 6 with a remainder of 213.
Put 6 as the next digit of the answer. 
Result so far: 1286.0
If we subtract 3450 from 3663, we get 213.
Grab the next digit (0) from the dividend, add it to 213, then carry on: 2130 / 575

On to step 7:
When dividing 2130 by 575, we get 3 with a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 12863.0
Subtract 1725 from 2130 to get 405.
Bring next digit (6) of the dividend behind the 405 and repeat the process: 4056 / 575

Let's proceed to step 8:
4056 divided by 575 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 128637.0
Subtract 4025 from 4056 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
575 goes into 310 0 times with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 128637.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
When dividing 3100 by 575, we get 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 128637.05
Deduct 2875 from 3100 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
575 can be fit into 2250 3 times, resulting in a remainder of 525.
The next digit of our result is 3. 
Result so far: 128637.053
If we subtract 1725 from 2250, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 12:
575 goes into 5250 9 times with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 128637.0539
Subtract 5175 from 5250 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
750 divided by 575 is 1 with a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 128637.05391
If we subtract 575 from 750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 14:
575 can be fit into 1750 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 128637.053913
If we take 1725 away from 1750, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 15:
The number 575 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 128637.053913
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
575 can be fit into 2500 4 times, resulting in a remainder of 200.
The next digit of our result is 4. 
Result so far: 128637.05391304
Deduct 2300 from 2500 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 128637.05391304, and the remainder is 2e-07.
