We divide 9297564 by 641
The aim is to understand the frequency of 641 in 9297564.

On to step 1:
641 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 641

Moving on to step 2:
641 can be fit into 92 0 times, resulting in a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 92 to get 92.
Include the next digit (9) from the dividend after 92, then repeat: 929 / 641

On to step 3:
641 can be fit into 929 1 times, resulting in a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 641 from 929, we get 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 641

Step 4:
The number 641 fits into 2887 4 times, leaving a remainder of 323.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 2564 from 2887 and we're left with 323.
Take the next digit (5) from the dividend and append it to 323, then repeat: 3235 / 641

Moving on to step 5:
641 goes into 3235 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
The remainder is 30 after subtracting 3205 from 3235.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 641

Step 6:
If we divide 306 by 641, we get 0 and a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 1450.0
The remainder is 306 after subtracting 0 from 306.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 641

Moving on to step 7:
641 can be fit into 3064 4 times, resulting in a remainder of 500.
Write down 4 as next digit of the result. 
Result so far: 14504.0
The remainder is 500 after subtracting 2564 from 3064.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 8:
641 can be fit into 5000 7 times, resulting in a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 14504.7
The remainder is 513 after subtracting 4487 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 9:
If we divide 5130 by 641, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 14504.78
If we take 5128 away from 5130, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 641, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14504.78
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 641, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 14504.78
Subtracting 0 from 200 leaves us 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 final outcome is 14504.78, with a leftover of 0.002.
