9158618 ÷ 989 
The aim is to understand the frequency of 989 in 9158618.

On to step 1:
If we divide 9 by 989, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 989

Moving on to step 2:
989 can be fit into 91 0 times, resulting in a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 989

Let's proceed to step 3:
When dividing 915 by 989, we get 0 with a remainder of 915.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 915 and we're left with 915.
Append the next digit (8) from the dividend to 915 and continue with: 9158 / 989

On to step 4:
When dividing 9158 by 989, we get 9 with a remainder of 257.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8901 from 9158, we get 257.
Grab the next digit (6) from the dividend, add it to 257, then carry on: 2576 / 989

Advancing to step 5:
989 goes into 2576 2 times with a remainder of 598.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 1978 from 2576, we get 598.
Append the next digit (1) from the dividend to 598 and continue with: 5981 / 989

On to step 6:
989 can be fit into 5981 6 times, resulting in a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 926.0
Subtract 5934 from 5981 to get 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 989

Moving on to step 7:
478 divided by 989 is 0 with a remainder of 478.
Use 0 as the next digit of our solution. 
Result so far: 9260.0
If we take 0 away from 478, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 8:
4780 divided by 989 is 4 with a remainder of 824.
Record the quotient 4 as the next digit in the result. 
Result so far: 9260.4
Subtracting 3956 from 4780 leaves us with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Moving on to step 9:
989 goes into 8240 8 times with a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 9260.48
The remainder is 328 after subtracting 7912 from 8240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 10:
If we divide 3280 by 989, we get 3 and a remainder of 313.
The number 3 becomes the next digit in our result. 
Result so far: 9260.483
If we take 2967 away from 3280, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 11:
989 can be fit into 3130 3 times, resulting in a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 9260.4833
The remainder is 163 after subtracting 2967 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Our division results in 9260.4833 with a remaining 0.00163.
