We're dividing 36521197 by 981 
The aim is to understand the frequency of 981 in 36521197.

On to step 1:
981 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 981

Moving on to step 2:
981 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 981

Let's proceed to step 3:
The number 981 fits into 365 0 times, leaving a remainder of 365.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 365, we get 365.
Grab the next digit (2) from the dividend, add it to 365, then carry on: 3652 / 981

Step 4:
When dividing 3652 by 981, we get 3 with a remainder of 709.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2943 from 3652 to get 709.
Grab the next digit (1) from the dividend, add it to 709, then carry on: 7091 / 981

Let's proceed to step 5:
If we divide 7091 by 981, we get 7 and a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 6867 from 7091 and we're left with 224.
Grab the next digit (1) from the dividend, add it to 224, then carry on: 2241 / 981

On to step 6:
When dividing 2241 by 981, we get 2 with a remainder of 279.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
Subtracting 1962 from 2241 leaves us with 279.
Include the next digit (9) from the dividend after 279, then repeat: 2799 / 981

Step 7:
2799 divided by 981 is 2 with a remainder of 837.
Use 2 as the next digit of our solution. 
Result so far: 3722.0
The remainder is 837 after subtracting 1962 from 2799.
Take the next digit (7) from the dividend and append it to 837, then repeat: 8377 / 981

Advancing to step 8:
8377 divided by 981 is 8 with a remainder of 529.
Put 8 as the next digit of the answer. 
Result so far: 37228.0
If we subtract 7848 from 8377, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 9:
981 can be fit into 5290 5 times, resulting in a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 37228.5
If we subtract 4905 from 5290, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 10:
3850 divided by 981 is 3 with a remainder of 907.
The number 3 becomes the next digit in our result. 
Result so far: 37228.53
Subtract 2943 from 3850 to get 907.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9070, and continue the process.

Going ahead to step 11:
If we divide 9070 by 981, we get 9 and a remainder of 241.
The next digit of our result is 9. 
Result so far: 37228.539
If we subtract 8829 from 9070, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 12:
2410 divided by 981 is 2 with a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 37228.5392
Deduct 1962 from 2410 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 13:
981 goes into 4480 4 times with a remainder of 556.
The next digit of our result is 4. 
Result so far: 37228.53924
The remainder is 556 after subtracting 3924 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 14:
If we divide 5560 by 981, we get 5 and a remainder of 655.
Put 5 as the next digit of the answer. 
Result so far: 37228.539245
The remainder is 655 after subtracting 4905 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 15:
If we divide 6550 by 981, we get 6 and a remainder of 664.
Record the quotient 6 as the next digit in the result. 
Result so far: 37228.5392456
The remainder is 664 after subtracting 5886 from 6550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 16:
When dividing 6640 by 981, we get 6 with a remainder of 754.
The number 6 becomes the next digit in our result. 
Result so far: 37228.53924566
If we subtract 5886 from 6640, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

The quotient of the division is 37228.53924566, and the remainder is 7.54e-07.
