We look at the division of 60354700 by 641 
The aim is to understand the frequency of 641 in 60354700.

Let's proceed to step 1:
When dividing 6 by 641, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 641

Advancing to step 2:
641 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 641

Step 3:
The number 641 fits into 603 0 times, leaving a remainder of 603.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 603, we get 603.
Fetch the next digit (5) from the dividend, attach it to 603 and continue: 6035 / 641

Moving on to step 4:
The number 641 fits into 6035 9 times, leaving a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 5769 from 6035 to get 266.
Take the next digit (4) from the dividend and append it to 266, then repeat: 2664 / 641

Moving on to step 5:
If we divide 2664 by 641, we get 4 and a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we take 2564 away from 2664, we end up with 100.
Fetch the next digit (7) from the dividend, attach it to 100 and continue: 1007 / 641

Let's proceed to step 6:
641 goes into 1007 1 times with a remainder of 366.
Put 1 as the next digit of the answer. 
Result so far: 941.0
Subtract 641 from 1007 to get 366.
Append the next digit (0) from the dividend to 366 and continue with: 3660 / 641

Going ahead to step 7:
3660 divided by 641 is 5 with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 9415.0
The remainder is 455 after subtracting 3205 from 3660.
Bring next digit (0) of the dividend behind the 455 and repeat the process: 4550 / 641

Advancing to step 8:
When dividing 4550 by 641, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 94157.0
Subtract 4487 from 4550 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
If we divide 630 by 641, we get 0 and a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 94157.0
The remainder is 630 after subtracting 0 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
If we divide 6300 by 641, we get 9 and a remainder of 531.
Use 9 as the next digit of our solution. 
Result so far: 94157.09
If we subtract 5769 from 6300, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 11:
641 goes into 5310 8 times with a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 94157.098
If we take 5128 away from 5310, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 12:
641 can be fit into 1820 2 times, resulting in a remainder of 538.
Put 2 as the next digit of the answer. 
Result so far: 94157.0982
The remainder is 538 after subtracting 1282 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 13:
When dividing 5380 by 641, we get 8 with a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 94157.09828
Subtracting 5128 from 5380 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 14:
641 can be fit into 2520 3 times, resulting in a remainder of 597.
Write down 3 as next digit of the result. 
Result so far: 94157.098283
If we take 1923 away from 2520, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 15:
641 goes into 5970 9 times with a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 94157.0982839
If we subtract 5769 from 5970, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 16:
If we divide 2010 by 641, we get 3 and a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 94157.09828393
Subtract 1923 from 2010 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final result is 94157.09828393 with a remainder of 8.7e-08.
