We divide 71944078 by 121
The aim is to understand the frequency of 121 in 71944078.

Let's proceed to step 1:
The number 121 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 121

Moving on to step 2:
121 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 121

Advancing to step 3:
When dividing 719 by 121, we get 5 with a remainder of 114.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 605 from 719 leaves us with 114.
Grab the next digit (4) from the dividend, add it to 114, then carry on: 1144 / 121

Going ahead to step 4:
1144 divided by 121 is 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtract 1089 from 1144 to get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 121

On to step 5:
When dividing 554 by 121, we get 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 594.0
Subtracting 484 from 554 leaves us with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 121

On to step 6:
If we divide 700 by 121, we get 5 and a remainder of 95.
The next digit of our result is 5. 
Result so far: 5945.0
The remainder is 95 after subtracting 605 from 700.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 121

Moving on to step 7:
957 divided by 121 is 7 with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 59457.0
Subtracting 847 from 957 leaves us with 110.
Bring next digit (8) of the dividend behind the 110 and repeat the process: 1108 / 121

Step 8:
If we divide 1108 by 121, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 594579.0
If we take 1089 away from 1108, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
121 goes into 190 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 594579.1
If we take 121 away from 190, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
121 goes into 690 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 594579.15
Subtract 605 from 690 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.

Moving on to step 11:
121 goes into 850 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 594579.157
If we take 847 away from 850, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
121 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 594579.157
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
If we divide 300 by 121, we get 2 and a remainder of 58.
The next digit of our result is 2. 
Result so far: 594579.15702
Deduct 242 from 300 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
If we divide 580 by 121, we get 4 and a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 594579.157024
The remainder is 96 after subtracting 484 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
The number 121 fits into 960 7 times, leaving a remainder of 113.
The next digit of our result is 7. 
Result so far: 594579.1570247
If we take 847 away from 960, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 16:
121 goes into 1130 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 594579.15702479
If we subtract 1089 from 1130, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 594579.15702479 with a remainder of 4.1e-08.
