40603099 ÷ 625 
The aim is to understand the frequency of 625 in 40603099.

Advancing to step 1:
4 divided by 625 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 625

Going ahead to step 2:
The number 625 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 625

Step 3:
625 can be fit into 406 0 times, resulting in a remainder of 406.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 406 to get 406.
Include the next digit (0) from the dividend after 406, then repeat: 4060 / 625

On to step 4:
625 can be fit into 4060 6 times, resulting in a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3750 from 4060, we get 310.
Bring next digit (3) of the dividend behind the 310 and repeat the process: 3103 / 625

Going ahead to step 5:
625 can be fit into 3103 4 times, resulting in a remainder of 603.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 2500 from 3103 and we're left with 603.
Take the next digit (0) from the dividend and append it to 603, then repeat: 6030 / 625

Going ahead to step 6:
625 goes into 6030 9 times with a remainder of 405.
Put 9 as the next digit of the answer. 
Result so far: 649.0
If we take 5625 away from 6030, we end up with 405.
Append the next digit (9) from the dividend to 405 and continue with: 4059 / 625

Step 7:
If we divide 4059 by 625, we get 6 and a remainder of 309.
Put 6 as the next digit of the answer. 
Result so far: 6496.0
The remainder is 309 after subtracting 3750 from 4059.
Bring next digit (9) of the dividend behind the 309 and repeat the process: 3099 / 625

Advancing to step 8:
The number 625 fits into 3099 4 times, leaving a remainder of 599.
Use 4 as the next digit of our solution. 
Result so far: 64964.0
Subtract 2500 from 3099 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 9:
When dividing 5990 by 625, we get 9 with a remainder of 365.
Record the quotient 9 as the next digit in the result. 
Result so far: 64964.9
If we subtract 5625 from 5990, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 10:
When dividing 3650 by 625, we get 5 with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 64964.95
Subtracting 3125 from 3650 leaves us with 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 11:
625 can be fit into 5250 8 times, resulting in a remainder of 250.
Write down 8 as next digit of the result. 
Result so far: 64964.958
If we subtract 5000 from 5250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
625 can be fit into 2500 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 64964.9584
Subtract 2500 from 2500 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
625 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64964.9584
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
625 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 64964.9584
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 64964.9584 with a remaining 0.0.
