Let's divide 971638 by 9
The aim is to understand the frequency of 9 in 971638.

Going ahead to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 9

Let's proceed to step 2:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 9

Moving on to step 3:
The number 9 fits into 71 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 63 from 71 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 9

Moving on to step 4:
9 can be fit into 86 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 1079.0
Deduct 81 from 86 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 9

Let's proceed to step 5:
9 can be fit into 53 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 10795.0
If we subtract 45 from 53, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 9

Let's proceed to step 6:
The number 9 fits into 88 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 107959.0
If we take 81 away from 88, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 107959.7
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
If we divide 70 by 9, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 107959.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 107959.77, and the remainder is 0.007.
