We look at the division of 37434004 by 121 
The aim is to understand the frequency of 121 in 37434004.

Going ahead to step 1:
The number 121 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 121

Step 2:
When dividing 37 by 121, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 121

Let's proceed to step 3:
121 can be fit into 374 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 363 away from 374, we end up with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 121

Moving on to step 4:
If we divide 113 by 121, we get 0 and a remainder of 113.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 113 after subtracting 0 from 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 121

Let's proceed to step 5:
When dividing 1134 by 121, we get 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Subtracting 1089 from 1134 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 121

On to step 6:
When dividing 450 by 121, we get 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 3093.0
The remainder is 87 after subtracting 363 from 450.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 121

Going ahead to step 7:
121 goes into 870 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 30937.0
If we take 847 away from 870, we end up with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 121

On to step 8:
234 divided by 121 is 1 with a remainder of 113.
Record the quotient 1 as the next digit in the result. 
Result so far: 309371.0
If we take 121 away from 234, 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.

Let's proceed to step 9:
If we divide 1130 by 121, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 309371.9
The remainder is 41 after subtracting 1089 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
If we divide 410 by 121, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 309371.93
Subtract 363 from 410 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
121 can be fit into 470 3 times, resulting in a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 309371.933
The remainder is 107 after subtracting 363 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

In conclusion, the division gives 309371.933 with a balance of 0.0107.
