We're dividing 11645051 by 986 
The aim is to understand the frequency of 986 in 11645051.

Advancing to step 1:
1 divided by 986 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 986

Advancing to step 2:
The number 986 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 986

Advancing to step 3:
When dividing 116 by 986, we get 0 with a remainder of 116.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 116 to get 116.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 986

Step 4:
986 can be fit into 1164 1 times, resulting in a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 986 from 1164, we get 178.
Bring next digit (5) of the dividend behind the 178 and repeat the process: 1785 / 986

Advancing to step 5:
When dividing 1785 by 986, we get 1 with a remainder of 799.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 986 away from 1785, we end up with 799.
Append the next digit (0) from the dividend to 799 and continue with: 7990 / 986

Let's proceed to step 6:
When dividing 7990 by 986, we get 8 with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we take 7888 away from 7990, we end up with 102.
Fetch the next digit (5) from the dividend, attach it to 102 and continue: 1025 / 986

Going ahead to step 7:
986 can be fit into 1025 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1181.0
Subtracting 986 from 1025 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 986

Moving on to step 8:
986 can be fit into 391 0 times, resulting in a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 11810.0
Deduct 0 from 391 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 9:
If we divide 3910 by 986, we get 3 and a remainder of 952.
Write down 3 as next digit of the result. 
Result so far: 11810.3
If we take 2958 away from 3910, we end up with 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

On to step 10:
When dividing 9520 by 986, we get 9 with a remainder of 646.
Put 9 as the next digit of the answer. 
Result so far: 11810.39
Deduct 8874 from 9520 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 11:
986 can be fit into 6460 6 times, resulting in a remainder of 544.
The next digit of our result is 6. 
Result so far: 11810.396
Subtract 5916 from 6460 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 12:
986 can be fit into 5440 5 times, resulting in a remainder of 510.
The next digit of our result is 5. 
Result so far: 11810.3965
If we take 4930 away from 5440, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 13:
986 can be fit into 5100 5 times, resulting in a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 11810.39655
Subtracting 4930 from 5100 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The quotient of the division is 11810.39655, and the remainder is 0.00017.
