We're dividing 31360643 by 986 
The aim is to understand the frequency of 986 in 31360643.

Step 1:
If we divide 3 by 986, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 986

On to step 2:
986 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 986

Moving on to step 3:
986 goes into 313 0 times with a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 313 and we're left with 313.
Bring next digit (6) of the dividend behind the 313 and repeat the process: 3136 / 986

Let's proceed to step 4:
3136 divided by 986 is 3 with a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2958 from 3136 leaves us with 178.
Include the next digit (0) from the dividend after 178, then repeat: 1780 / 986

Moving on to step 5:
If we divide 1780 by 986, we get 1 and a remainder of 794.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 986 from 1780 leaves us with 794.
Append the next digit (6) from the dividend to 794 and continue with: 7946 / 986

Moving on to step 6:
7946 divided by 986 is 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 318.0
If we subtract 7888 from 7946, we get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 986

Going ahead to step 7:
986 can be fit into 584 0 times, resulting in a remainder of 584.
Write down 0 as next digit of the result. 
Result so far: 3180.0
If we subtract 0 from 584, we get 584.
Include the next digit (3) from the dividend after 584, then repeat: 5843 / 986

On to step 8:
986 can be fit into 5843 5 times, resulting in a remainder of 913.
Record the quotient 5 as the next digit in the result. 
Result so far: 31805.0
Subtract 4930 from 5843 to get 913.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9130, and continue the process.

Step 9:
9130 divided by 986 is 9 with a remainder of 256.
The next digit of our result is 9. 
Result so far: 31805.9
Subtract 8874 from 9130 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 10:
When dividing 2560 by 986, we get 2 with a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 31805.92
Subtracting 1972 from 2560 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 11:
5880 divided by 986 is 5 with a remainder of 950.
Use 5 as the next digit of our solution. 
Result so far: 31805.925
If we take 4930 away from 5880, we end up with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Let's proceed to step 12:
If we divide 9500 by 986, we get 9 and a remainder of 626.
Record the quotient 9 as the next digit in the result. 
Result so far: 31805.9259
If we subtract 8874 from 9500, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 13:
6260 divided by 986 is 6 with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 31805.92596
Subtract 5916 from 6260 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 14:
986 can be fit into 3440 3 times, resulting in a remainder of 482.
The next digit of our result is 3. 
Result so far: 31805.925963
Subtract 2958 from 3440 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 15:
986 can be fit into 4820 4 times, resulting in a remainder of 876.
Use 4 as the next digit of our solution. 
Result so far: 31805.9259634
Subtracting 3944 from 4820 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

On to step 16:
986 can be fit into 8760 8 times, resulting in a remainder of 872.
Put 8 as the next digit of the answer. 
Result so far: 31805.92596348
If we take 7888 away from 8760, we end up with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

After the division, we end up with 31805.92596348 and a remainder of 8.72e-07.
