We divide 52713200 by 641
The aim is to understand the frequency of 641 in 52713200.

Going ahead to step 1:
5 divided by 641 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 641

Let's proceed to step 2:
When dividing 52 by 641, we get 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 641

Advancing to step 3:
If we divide 527 by 641, we get 0 and a remainder of 527.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 527, we get 527.
Grab the next digit (1) from the dividend, add it to 527, then carry on: 5271 / 641

Going ahead to step 4:
641 can be fit into 5271 8 times, resulting in a remainder of 143.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5128 from 5271 to get 143.
Fetch the next digit (3) from the dividend, attach it to 143 and continue: 1433 / 641

Going ahead to step 5:
If we divide 1433 by 641, we get 2 and a remainder of 151.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 1282 from 1433 leaves us with 151.
Fetch the next digit (2) from the dividend, attach it to 151 and continue: 1512 / 641

Advancing to step 6:
1512 divided by 641 is 2 with a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 822.0
Subtracting 1282 from 1512 leaves us with 230.
Grab the next digit (0) from the dividend, add it to 230, then carry on: 2300 / 641

Let's proceed to step 7:
If we divide 2300 by 641, we get 3 and a remainder of 377.
Record the quotient 3 as the next digit in the result. 
Result so far: 8223.0
Subtracting 1923 from 2300 leaves us with 377.
Include the next digit (0) from the dividend after 377, then repeat: 3770 / 641

Going ahead to step 8:
3770 divided by 641 is 5 with a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 82235.0
Subtract 3205 from 3770 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 9:
5650 divided by 641 is 8 with a remainder of 522.
Put 8 as the next digit of the answer. 
Result so far: 82235.8
If we take 5128 away from 5650, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 10:
If we divide 5220 by 641, we get 8 and a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 82235.88
Subtract 5128 from 5220 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 82235.88 with a remainder of 0.092.
