We're dividing 3976783 by 981 
The aim is to understand the frequency of 981 in 3976783.

Let's proceed to step 1:
3 divided by 981 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 981

Moving on to step 2:
If we divide 39 by 981, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 981

Moving on to step 3:
When dividing 397 by 981, we get 0 with a remainder of 397.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 397 leaves us with 397.
Bring next digit (6) of the dividend behind the 397 and repeat the process: 3976 / 981

Step 4:
3976 divided by 981 is 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3924 from 3976 leaves us with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 981

Advancing to step 5:
981 can be fit into 527 0 times, resulting in a remainder of 527.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 527 to get 527.
Bring next digit (8) of the dividend behind the 527 and repeat the process: 5278 / 981

On to step 6:
If we divide 5278 by 981, we get 5 and a remainder of 373.
Use 5 as the next digit of our solution. 
Result so far: 405.0
If we subtract 4905 from 5278, we get 373.
Fetch the next digit (3) from the dividend, attach it to 373 and continue: 3733 / 981

Let's proceed to step 7:
3733 divided by 981 is 3 with a remainder of 790.
The next digit of our result is 3. 
Result so far: 4053.0
Subtracting 2943 from 3733 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 8:
The number 981 fits into 7900 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 4053.8
Deduct 7848 from 7900 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
981 goes into 520 0 times with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 4053.8
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
If we divide 5200 by 981, we get 5 and a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 4053.805
The remainder is 295 after subtracting 4905 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 11:
981 goes into 2950 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4053.8053
If we take 2943 away from 2950, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 981, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4053.8053
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
The number 981 fits into 700 0 times, leaving a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 4053.8053
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 4053.8053, and the remainder is 7e-05.
