Let's divide 30621385 by 657
The aim is to understand the frequency of 657 in 30621385.

Step 1:
The number 657 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 657

Let's proceed to step 2:
30 divided by 657 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 657

Going ahead to step 3:
657 can be fit into 306 0 times, resulting in a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 306 after subtracting 0 from 306.
Fetch the next digit (2) from the dividend, attach it to 306 and continue: 3062 / 657

Advancing to step 4:
3062 divided by 657 is 4 with a remainder of 434.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2628 from 3062, we get 434.
Include the next digit (1) from the dividend after 434, then repeat: 4341 / 657

Step 5:
657 can be fit into 4341 6 times, resulting in a remainder of 399.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 3942 away from 4341, we end up with 399.
Bring next digit (3) of the dividend behind the 399 and repeat the process: 3993 / 657

Going ahead to step 6:
657 can be fit into 3993 6 times, resulting in a remainder of 51.
The next digit of our result is 6. 
Result so far: 466.0
If we subtract 3942 from 3993, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 657

Going ahead to step 7:
657 can be fit into 518 0 times, resulting in a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 4660.0
Subtract 0 from 518 to get 518.
Grab the next digit (5) from the dividend, add it to 518, then carry on: 5185 / 657

Advancing to step 8:
When dividing 5185 by 657, we get 7 with a remainder of 586.
Use 7 as the next digit of our solution. 
Result so far: 46607.0
The remainder is 586 after subtracting 4599 from 5185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 9:
657 goes into 5860 8 times with a remainder of 604.
The next digit of our result is 8. 
Result so far: 46607.8
The remainder is 604 after subtracting 5256 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 10:
657 goes into 6040 9 times with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 46607.89
Subtract 5913 from 6040 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 11:
657 goes into 1270 1 times with a remainder of 613.
The next digit of our result is 1. 
Result so far: 46607.891
The remainder is 613 after subtracting 657 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Advancing to step 12:
6130 divided by 657 is 9 with a remainder of 217.
Record the quotient 9 as the next digit in the result. 
Result so far: 46607.8919
If we take 5913 away from 6130, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 13:
When dividing 2170 by 657, we get 3 with a remainder of 199.
Record the quotient 3 as the next digit in the result. 
Result so far: 46607.89193
Subtracting 1971 from 2170 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 14:
657 goes into 1990 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 46607.891933
If we subtract 1971 from 1990, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 46607.891933 with a remaining 1.9e-06.
