We're dividing 83916318 by 986 
The aim is to understand the frequency of 986 in 83916318.

Step 1:
When dividing 8 by 986, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 986

Let's proceed to step 2:
986 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 986

Moving on to step 3:
When dividing 839 by 986, we get 0 with a remainder of 839.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 839 leaves us with 839.
Append the next digit (1) from the dividend to 839 and continue with: 8391 / 986

Step 4:
The number 986 fits into 8391 8 times, leaving a remainder of 503.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7888 from 8391 and we're left with 503.
Include the next digit (6) from the dividend after 503, then repeat: 5036 / 986

Let's proceed to step 5:
If we divide 5036 by 986, we get 5 and a remainder of 106.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 4930 from 5036, we get 106.
Append the next digit (3) from the dividend to 106 and continue with: 1063 / 986

Moving on to step 6:
When dividing 1063 by 986, we get 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 851.0
Deduct 986 from 1063 and we're left with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 986

On to step 7:
If we divide 771 by 986, we get 0 and a remainder of 771.
The next digit of our result is 0. 
Result so far: 8510.0
Deduct 0 from 771 and we're left with 771.
Bring next digit (8) of the dividend behind the 771 and repeat the process: 7718 / 986

Going ahead to step 8:
The number 986 fits into 7718 7 times, leaving a remainder of 816.
The next digit of our result is 7. 
Result so far: 85107.0
Subtracting 6902 from 7718 leaves us with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 9:
8160 divided by 986 is 8 with a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 85107.8
The remainder is 272 after subtracting 7888 from 8160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
2720 divided by 986 is 2 with a remainder of 748.
Use 2 as the next digit of our solution. 
Result so far: 85107.82
Deduct 1972 from 2720 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Let's proceed to step 11:
If we divide 7480 by 986, we get 7 and a remainder of 578.
Record the quotient 7 as the next digit in the result. 
Result so far: 85107.827
If we take 6902 away from 7480, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 12:
986 can be fit into 5780 5 times, resulting in a remainder of 850.
Use 5 as the next digit of our solution. 
Result so far: 85107.8275
If we subtract 4930 from 5780, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Let's proceed to step 13:
986 goes into 8500 8 times with a remainder of 612.
Use 8 as the next digit of our solution. 
Result so far: 85107.82758
If we subtract 7888 from 8500, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 14:
When dividing 6120 by 986, we get 6 with a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 85107.827586
If we subtract 5916 from 6120, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 15:
The number 986 fits into 2040 2 times, leaving a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 85107.8275862
Subtracting 1972 from 2040 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 16:
If we divide 680 by 986, we get 0 and a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 85107.8275862
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

After the division, we end up with 85107.8275862 and a remainder of 6.8e-07.
