We look at the division of 39673300 by 981 
The aim is to understand the frequency of 981 in 39673300.

Moving on to step 1:
When dividing 3 by 981, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 981

Moving on to step 2:
981 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 981

Step 3:
981 can be fit into 396 0 times, resulting in a remainder of 396.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Append the next digit (7) from the dividend to 396 and continue with: 3967 / 981

Let's proceed to step 4:
3967 divided by 981 is 4 with a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 43 after subtracting 3924 from 3967.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 981

Step 5:
When dividing 433 by 981, we get 0 with a remainder of 433.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 433 after subtracting 0 from 433.
Grab the next digit (3) from the dividend, add it to 433, then carry on: 4333 / 981

Moving on to step 6:
981 can be fit into 4333 4 times, resulting in a remainder of 409.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we subtract 3924 from 4333, we get 409.
Take the next digit (0) from the dividend and append it to 409, then repeat: 4090 / 981

Advancing to step 7:
981 goes into 4090 4 times with a remainder of 166.
The next digit of our result is 4. 
Result so far: 4044.0
Subtract 3924 from 4090 to get 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 981

Advancing to step 8:
1660 divided by 981 is 1 with a remainder of 679.
The number 1 becomes the next digit in our result. 
Result so far: 40441.0
Subtract 981 from 1660 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

On to step 9:
981 goes into 6790 6 times with a remainder of 904.
Put 6 as the next digit of the answer. 
Result so far: 40441.6
If we take 5886 away from 6790, we end up with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

On to step 10:
The number 981 fits into 9040 9 times, leaving a remainder of 211.
The next digit of our result is 9. 
Result so far: 40441.69
Subtracting 8829 from 9040 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 11:
981 can be fit into 2110 2 times, resulting in a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 40441.692
The remainder is 148 after subtracting 1962 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 12:
When dividing 1480 by 981, we get 1 with a remainder of 499.
Record the quotient 1 as the next digit in the result. 
Result so far: 40441.6921
Subtracting 981 from 1480 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 13:
If we divide 4990 by 981, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 40441.69215
Subtract 4905 from 4990 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 14:
850 divided by 981 is 0 with a remainder of 850.
The next digit of our result is 0. 
Result so far: 40441.69215
Deduct 0 from 850 and we're left with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 15:
When dividing 8500 by 981, we get 8 with a remainder of 652.
Put 8 as the next digit of the answer. 
Result so far: 40441.6921508
The remainder is 652 after subtracting 7848 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 16:
When dividing 6520 by 981, we get 6 with a remainder of 634.
Write down 6 as next digit of the result. 
Result so far: 40441.69215086
Deduct 5886 from 6520 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

The final outcome is 40441.69215086, with a leftover of 6.34e-07.
