We divide 23990971 by 979
The aim is to understand the frequency of 979 in 23990971.

Going ahead to step 1:
If we divide 2 by 979, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 979

Advancing to step 2:
23 divided by 979 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 979

Moving on to step 3:
979 can be fit into 239 0 times, resulting in a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 239 after subtracting 0 from 239.
Append the next digit (9) from the dividend to 239 and continue with: 2399 / 979

On to step 4:
The number 979 fits into 2399 2 times, leaving a remainder of 441.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1958 from 2399, we get 441.
Fetch the next digit (0) from the dividend, attach it to 441 and continue: 4410 / 979

Advancing to step 5:
979 goes into 4410 4 times with a remainder of 494.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 494 after subtracting 3916 from 4410.
Take the next digit (9) from the dividend and append it to 494, then repeat: 4949 / 979

Step 6:
979 can be fit into 4949 5 times, resulting in a remainder of 54.
The next digit of our result is 5. 
Result so far: 245.0
Deduct 4895 from 4949 and we're left with 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 979

Going ahead to step 7:
When dividing 547 by 979, we get 0 with a remainder of 547.
Record the quotient 0 as the next digit in the result. 
Result so far: 2450.0
Deduct 0 from 547 and we're left with 547.
Append the next digit (1) from the dividend to 547 and continue with: 5471 / 979

Moving on to step 8:
979 goes into 5471 5 times with a remainder of 576.
Use 5 as the next digit of our solution. 
Result so far: 24505.0
If we take 4895 away from 5471, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 9:
When dividing 5760 by 979, we get 5 with a remainder of 865.
The next digit of our result is 5. 
Result so far: 24505.5
If we take 4895 away from 5760, we end up with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Let's proceed to step 10:
If we divide 8650 by 979, we get 8 and a remainder of 818.
The number 8 becomes the next digit in our result. 
Result so far: 24505.58
If we subtract 7832 from 8650, we get 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

On to step 11:
When dividing 8180 by 979, we get 8 with a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 24505.588
Deduct 7832 from 8180 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The quotient of the division is 24505.588, and the remainder is 0.0348.
