Let's divide 56907636 by 121
The aim is to understand the frequency of 121 in 56907636.

Let's proceed to step 1:
When dividing 5 by 121, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 121

Going ahead to step 2:
If we divide 56 by 121, we get 0 and a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 121

Let's proceed to step 3:
121 can be fit into 569 4 times, resulting in a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 484 from 569, we get 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 121

Step 4:
850 divided by 121 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 847 from 850 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 121

On to step 5:
If we divide 37 by 121, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 470.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 121

On to step 6:
If we divide 376 by 121, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4703.0
Subtract 363 from 376 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 121

Going ahead to step 7:
133 divided by 121 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 47031.0
Subtract 121 from 133 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 121

Going ahead to step 8:
The number 121 fits into 126 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 470311.0
Deduct 121 from 126 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 121 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 470311.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
121 can be fit into 500 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 470311.04
Subtract 484 from 500 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
121 can be fit into 160 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 470311.041
Deduct 121 from 160 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
The number 121 fits into 390 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 470311.0413
Deduct 363 from 390 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
When dividing 270 by 121, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 470311.04132
Subtract 242 from 270 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
When dividing 280 by 121, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 470311.041322
Subtract 242 from 280 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 470311.041322 and a remainder of 3.8e-06.
