Let's divide 915191 by 986
The aim is to understand the frequency of 986 in 915191.

Going ahead to step 1:
If we divide 9 by 986, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 986

Going ahead to step 2:
986 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 986

Let's proceed to step 3:
When dividing 915 by 986, we get 0 with a remainder of 915.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 915 and we're left with 915.
Append the next digit (1) from the dividend to 915 and continue with: 9151 / 986

Advancing to step 4:
986 can be fit into 9151 9 times, resulting in a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8874 from 9151, we get 277.
Bring next digit (9) of the dividend behind the 277 and repeat the process: 2779 / 986

On to step 5:
2779 divided by 986 is 2 with a remainder of 807.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtract 1972 from 2779 to get 807.
Include the next digit (1) from the dividend after 807, then repeat: 8071 / 986

On to step 6:
The number 986 fits into 8071 8 times, leaving a remainder of 183.
Write down 8 as next digit of the result. 
Result so far: 928.0
Subtracting 7888 from 8071 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 7:
If we divide 1830 by 986, we get 1 and a remainder of 844.
Use 1 as the next digit of our solution. 
Result so far: 928.1
Deduct 986 from 1830 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Moving on to step 8:
When dividing 8440 by 986, we get 8 with a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 928.18
Subtract 7888 from 8440 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 9:
If we divide 5520 by 986, we get 5 and a remainder of 590.
Record the quotient 5 as the next digit in the result. 
Result so far: 928.185
If we subtract 4930 from 5520, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 10:
986 goes into 5900 5 times with a remainder of 970.
Put 5 as the next digit of the answer. 
Result so far: 928.1855
Subtract 4930 from 5900 to get 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

The quotient of the division is 928.1855, and the remainder is 0.0097.
