We're dividing 52950553 by 121 
The aim is to understand the frequency of 121 in 52950553.

Advancing to step 1:
The number 121 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 121

Let's proceed to step 2:
52 divided by 121 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 121

Advancing to step 3:
The number 121 fits into 529 4 times, leaving a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 45 after subtracting 484 from 529.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 121

Let's proceed to step 4:
121 goes into 455 3 times with a remainder of 92.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 363 from 455 and we're left with 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 121

Advancing to step 5:
The number 121 fits into 920 7 times, leaving a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 437.0
The remainder is 73 after subtracting 847 from 920.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 121

On to step 6:
735 divided by 121 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 4376.0
Deduct 726 from 735 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 121

Let's proceed to step 7:
95 divided by 121 is 0 with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 43760.0
Subtract 0 from 95 to get 95.
Take the next digit (3) from the dividend and append it to 95, then repeat: 953 / 121

Advancing to step 8:
When dividing 953 by 121, we get 7 with a remainder of 106.
The next digit of our result is 7. 
Result so far: 437607.0
Deduct 847 from 953 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 9:
1060 divided by 121 is 8 with a remainder of 92.
The next digit of our result is 8. 
Result so far: 437607.8
If we subtract 968 from 1060, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
The number 121 fits into 920 7 times, leaving a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 437607.87
Deduct 847 from 920 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
When dividing 730 by 121, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 437607.876
Deduct 726 from 730 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
121 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 437607.876
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 121, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 437607.87603
Deduct 363 from 400 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
370 divided by 121 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 437607.876033
The remainder is 7 after subtracting 363 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 437607.876033, and the remainder is 7e-07.
