We're dividing 52886065 by 121 
The aim is to understand the frequency of 121 in 52886065.

On to step 1:
The number 121 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 121

On to step 2:
When dividing 52 by 121, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 121

Advancing to step 3:
The number 121 fits into 528 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 484 away from 528, we end up with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 121

Step 4:
When dividing 448 by 121, we get 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 363 from 448 leaves us with 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 121

Advancing to step 5:
856 divided by 121 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
The remainder is 9 after subtracting 847 from 856.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 121

Step 6:
90 divided by 121 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 4370.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 121

Let's proceed to step 7:
906 divided by 121 is 7 with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 43707.0
Subtracting 847 from 906 leaves us with 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 121

Let's proceed to step 8:
595 divided by 121 is 4 with a remainder of 111.
The next digit of our result is 4. 
Result so far: 437074.0
Subtracting 484 from 595 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
If we divide 1110 by 121, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 437074.9
Deduct 1089 from 1110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
210 divided by 121 is 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 437074.91
Subtracting 121 from 210 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 11:
121 goes into 890 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 437074.917
If we subtract 847 from 890, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
430 divided by 121 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 437074.9173
The remainder is 67 after subtracting 363 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
When dividing 670 by 121, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 437074.91735
Deduct 605 from 670 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
The number 121 fits into 650 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 437074.917355
If we subtract 605 from 650, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 437074.917355, with a leftover of 4.5e-06.
