We divide 68641898 by 573
The aim is to understand the frequency of 573 in 68641898.

Moving on to step 1:
When dividing 6 by 573, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 573

On to step 2:
68 divided by 573 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 573

Advancing to step 3:
573 can be fit into 686 1 times, resulting in a remainder of 113.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 573 away from 686, we end up with 113.
Fetch the next digit (4) from the dividend, attach it to 113 and continue: 1134 / 573

Let's proceed to step 4:
The number 573 fits into 1134 1 times, leaving a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 561 after subtracting 573 from 1134.
Grab the next digit (1) from the dividend, add it to 561, then carry on: 5611 / 573

Going ahead to step 5:
The number 573 fits into 5611 9 times, leaving a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we take 5157 away from 5611, we end up with 454.
Take the next digit (8) from the dividend and append it to 454, then repeat: 4548 / 573

Advancing to step 6:
4548 divided by 573 is 7 with a remainder of 537.
Write down 7 as next digit of the result. 
Result so far: 1197.0
Subtracting 4011 from 4548 leaves us with 537.
Include the next digit (9) from the dividend after 537, then repeat: 5379 / 573

Moving on to step 7:
The number 573 fits into 5379 9 times, leaving a remainder of 222.
Use 9 as the next digit of our solution. 
Result so far: 11979.0
If we subtract 5157 from 5379, we get 222.
Bring next digit (8) of the dividend behind the 222 and repeat the process: 2228 / 573

Let's proceed to step 8:
573 can be fit into 2228 3 times, resulting in a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 119793.0
Deduct 1719 from 2228 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 9:
If we divide 5090 by 573, we get 8 and a remainder of 506.
Put 8 as the next digit of the answer. 
Result so far: 119793.8
If we take 4584 away from 5090, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 10:
When dividing 5060 by 573, we get 8 with a remainder of 476.
Use 8 as the next digit of our solution. 
Result so far: 119793.88
The remainder is 476 after subtracting 4584 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

After the division, we end up with 119793.88 and a remainder of 0.476.
