We look at the division of 5299390 by 641 
The aim is to understand the frequency of 641 in 5299390.

Moving on to step 1:
The number 641 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 641

Moving on to step 2:
641 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 641

Step 3:
When dividing 529 by 641, we get 0 with a remainder of 529.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 529 leaves us with 529.
Fetch the next digit (9) from the dividend, attach it to 529 and continue: 5299 / 641

Going ahead to step 4:
The number 641 fits into 5299 8 times, leaving a remainder of 171.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 171 after subtracting 5128 from 5299.
Append the next digit (3) from the dividend to 171 and continue with: 1713 / 641

Going ahead to step 5:
641 goes into 1713 2 times with a remainder of 431.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 1282 from 1713 to get 431.
Grab the next digit (9) from the dividend, add it to 431, then carry on: 4319 / 641

Moving on to step 6:
641 goes into 4319 6 times with a remainder of 473.
Put 6 as the next digit of the answer. 
Result so far: 826.0
Subtracting 3846 from 4319 leaves us with 473.
Take the next digit (0) from the dividend and append it to 473, then repeat: 4730 / 641

Let's proceed to step 7:
The number 641 fits into 4730 7 times, leaving a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 8267.0
If we subtract 4487 from 4730, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 8:
If we divide 2430 by 641, we get 3 and a remainder of 507.
Put 3 as the next digit of the answer. 
Result so far: 8267.3
The remainder is 507 after subtracting 1923 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 9:
When dividing 5070 by 641, we get 7 with a remainder of 583.
Record the quotient 7 as the next digit in the result. 
Result so far: 8267.37
Subtract 4487 from 5070 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 10:
If we divide 5830 by 641, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 8267.379
The remainder is 61 after subtracting 5769 from 5830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
641 can be fit into 610 0 times, resulting in a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 8267.379
Deduct 0 from 610 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 12:
641 can be fit into 6100 9 times, resulting in a remainder of 331.
Use 9 as the next digit of our solution. 
Result so far: 8267.37909
Subtract 5769 from 6100 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 13:
641 can be fit into 3310 5 times, resulting in a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 8267.379095
If we take 3205 away from 3310, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 14:
641 goes into 1050 1 times with a remainder of 409.
The number 1 becomes the next digit in our result. 
Result so far: 8267.3790951
Deduct 641 from 1050 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 15:
When dividing 4090 by 641, we get 6 with a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 8267.37909516
If we subtract 3846 from 4090, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 8267.37909516, and the remainder is 2.44e-07.
