61371539 ÷ 606 
The aim is to understand the frequency of 606 in 61371539.

On to step 1:
When dividing 6 by 606, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 606

Advancing to step 2:
When dividing 61 by 606, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 606

Going ahead to step 3:
606 goes into 613 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 606 from 613 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 606

Moving on to step 4:
If we divide 77 by 606, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 77 to get 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 606

On to step 5:
606 goes into 771 1 times with a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 606 from 771 leaves us with 165.
Append the next digit (5) from the dividend to 165 and continue with: 1655 / 606

Going ahead to step 6:
606 can be fit into 1655 2 times, resulting in a remainder of 443.
Record the quotient 2 as the next digit in the result. 
Result so far: 1012.0
Subtract 1212 from 1655 to get 443.
Append the next digit (3) from the dividend to 443 and continue with: 4433 / 606

On to step 7:
606 goes into 4433 7 times with a remainder of 191.
Use 7 as the next digit of our solution. 
Result so far: 10127.0
Subtracting 4242 from 4433 leaves us with 191.
Fetch the next digit (9) from the dividend, attach it to 191 and continue: 1919 / 606

Let's proceed to step 8:
1919 divided by 606 is 3 with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 101273.0
Subtracting 1818 from 1919 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
When dividing 1010 by 606, we get 1 with a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 101273.1
Subtracting 606 from 1010 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 10:
606 can be fit into 4040 6 times, resulting in a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 101273.16
Deduct 3636 from 4040 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
4040 divided by 606 is 6 with a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 101273.166
Subtract 3636 from 4040 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The quotient of the division is 101273.166, and the remainder is 0.0404.
