We look at the division of 86997927 by 986 
The aim is to understand the frequency of 986 in 86997927.

Step 1:
The number 986 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 986

Going ahead to step 2:
When dividing 86 by 986, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 986

Going ahead to step 3:
When dividing 869 by 986, we get 0 with a remainder of 869.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 869 to get 869.
Bring next digit (9) of the dividend behind the 869 and repeat the process: 8699 / 986

Step 4:
The number 986 fits into 8699 8 times, leaving a remainder of 811.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7888 away from 8699, we end up with 811.
Append the next digit (7) from the dividend to 811 and continue with: 8117 / 986

Let's proceed to step 5:
When dividing 8117 by 986, we get 8 with a remainder of 229.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 229 after subtracting 7888 from 8117.
Take the next digit (9) from the dividend and append it to 229, then repeat: 2299 / 986

On to step 6:
986 can be fit into 2299 2 times, resulting in a remainder of 327.
Write down 2 as next digit of the result. 
Result so far: 882.0
Subtract 1972 from 2299 to get 327.
Append the next digit (2) from the dividend to 327 and continue with: 3272 / 986

Moving on to step 7:
986 can be fit into 3272 3 times, resulting in a remainder of 314.
Put 3 as the next digit of the answer. 
Result so far: 8823.0
If we subtract 2958 from 3272, we get 314.
Fetch the next digit (7) from the dividend, attach it to 314 and continue: 3147 / 986

Moving on to step 8:
986 can be fit into 3147 3 times, resulting in a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 88233.0
If we subtract 2958 from 3147, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
If we divide 1890 by 986, we get 1 and a remainder of 904.
The number 1 becomes the next digit in our result. 
Result so far: 88233.1
Deduct 986 from 1890 and we're left with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Let's proceed to step 10:
9040 divided by 986 is 9 with a remainder of 166.
Write down 9 as next digit of the result. 
Result so far: 88233.19
Subtract 8874 from 9040 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
986 can be fit into 1660 1 times, resulting in a remainder of 674.
Put 1 as the next digit of the answer. 
Result so far: 88233.191
Deduct 986 from 1660 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

On to step 12:
The number 986 fits into 6740 6 times, leaving a remainder of 824.
Put 6 as the next digit of the answer. 
Result so far: 88233.1916
If we take 5916 away from 6740, we end up 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.

Step 13:
8240 divided by 986 is 8 with a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 88233.19168
Subtracting 7888 from 8240 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
When dividing 3520 by 986, we get 3 with a remainder of 562.
The next digit of our result is 3. 
Result so far: 88233.191683
Subtract 2958 from 3520 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 15:
5620 divided by 986 is 5 with a remainder of 690.
Put 5 as the next digit of the answer. 
Result so far: 88233.1916835
Deduct 4930 from 5620 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 16:
986 can be fit into 6900 6 times, resulting in a remainder of 984.
Record the quotient 6 as the next digit in the result. 
Result so far: 88233.19168356
Deduct 5916 from 6900 and we're left with 984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9840, and continue the process.

The quotient of the division is 88233.19168356, and the remainder is 9.84e-07.
