We're dividing 60780309 by 981 
The aim is to understand the frequency of 981 in 60780309.

Let's proceed to step 1:
If we divide 6 by 981, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 981

Advancing to step 2:
981 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 981

Advancing to step 3:
The number 981 fits into 607 0 times, leaving a remainder of 607.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 607 after subtracting 0 from 607.
Grab the next digit (8) from the dividend, add it to 607, then carry on: 6078 / 981

Step 4:
The number 981 fits into 6078 6 times, leaving a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 5886 from 6078 leaves us with 192.
Take the next digit (0) from the dividend and append it to 192, then repeat: 1920 / 981

Going ahead to step 5:
If we divide 1920 by 981, we get 1 and a remainder of 939.
The next digit of our result is 1. 
Result so far: 61.0
The remainder is 939 after subtracting 981 from 1920.
Bring next digit (3) of the dividend behind the 939 and repeat the process: 9393 / 981

Step 6:
The number 981 fits into 9393 9 times, leaving a remainder of 564.
The next digit of our result is 9. 
Result so far: 619.0
If we take 8829 away from 9393, we end up with 564.
Include the next digit (0) from the dividend after 564, then repeat: 5640 / 981

On to step 7:
981 goes into 5640 5 times with a remainder of 735.
Put 5 as the next digit of the answer. 
Result so far: 6195.0
The remainder is 735 after subtracting 4905 from 5640.
Fetch the next digit (9) from the dividend, attach it to 735 and continue: 7359 / 981

Advancing to step 8:
981 can be fit into 7359 7 times, resulting in a remainder of 492.
Write down 7 as next digit of the result. 
Result so far: 61957.0
Subtract 6867 from 7359 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 9:
4920 divided by 981 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 61957.5
Deduct 4905 from 4920 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 981 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 61957.5
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
When dividing 1500 by 981, we get 1 with a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 61957.501
If we take 981 away from 1500, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 12:
When dividing 5190 by 981, we get 5 with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 61957.5015
If we subtract 4905 from 5190, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 13:
The number 981 fits into 2850 2 times, leaving a remainder of 888.
The number 2 becomes the next digit in our result. 
Result so far: 61957.50152
The remainder is 888 after subtracting 1962 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

On to step 14:
If we divide 8880 by 981, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 61957.501529
If we subtract 8829 from 8880, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 15:
510 divided by 981 is 0 with a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 61957.501529
If we take 0 away from 510, 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.

On to step 16:
The number 981 fits into 5100 5 times, leaving a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 61957.50152905
Subtracting 4905 from 5100 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 61957.50152905, with a leftover of 1.95e-07.
