We're dividing 71171962 by 123 
The aim is to understand the frequency of 123 in 71171962.

Advancing to step 1:
If we divide 7 by 123, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 123

Going ahead to step 2:
If we divide 71 by 123, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 123

Step 3:
123 goes into 711 5 times with a remainder of 96.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 615 from 711 and we're left with 96.
Append the next digit (7) from the dividend to 96 and continue with: 967 / 123

Advancing to step 4:
When dividing 967 by 123, we get 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Deduct 861 from 967 and we're left with 106.
Fetch the next digit (1) from the dividend, attach it to 106 and continue: 1061 / 123

Going ahead to step 5:
1061 divided by 123 is 8 with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 578.0
If we subtract 984 from 1061, we get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 123

Let's proceed to step 6:
779 divided by 123 is 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 5786.0
The remainder is 41 after subtracting 738 from 779.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 123

Going ahead to step 7:
123 can be fit into 416 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 57863.0
If we take 369 away from 416, we end up with 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 123

On to step 8:
When dividing 472 by 123, we get 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 578633.0
The remainder is 103 after subtracting 369 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 9:
123 goes into 1030 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 578633.8
Subtract 984 from 1030 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
460 divided by 123 is 3 with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 578633.83
The remainder is 91 after subtracting 369 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 11:
123 can be fit into 910 7 times, resulting in a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 578633.837
Deduct 861 from 910 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
123 goes into 490 3 times with a remainder of 121.
The next digit of our result is 3. 
Result so far: 578633.8373
If we subtract 369 from 490, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 13:
123 goes into 1210 9 times with a remainder of 103.
The next digit of our result is 9. 
Result so far: 578633.83739
If we take 1107 away from 1210, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 14:
1030 divided by 123 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 578633.837398
Deduct 984 from 1030 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 15:
If we divide 460 by 123, we get 3 and a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 578633.8373983
If we take 369 away from 460, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 16:
123 goes into 910 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 578633.83739837
If we take 861 away from 910, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 578633.83739837 and a remainder of 4.9e-08.
