We look at the division of 39223629 by 955 
The aim is to understand the frequency of 955 in 39223629.

Going ahead to step 1:
955 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 955

Step 2:
If we divide 39 by 955, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 955

Step 3:
955 can be fit into 392 0 times, resulting in a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 392, we get 392.
Include the next digit (2) from the dividend after 392, then repeat: 3922 / 955

Moving on to step 4:
The number 955 fits into 3922 4 times, leaving a remainder of 102.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3820 from 3922 to get 102.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 955

Advancing to step 5:
955 can be fit into 1023 1 times, resulting in a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 955 from 1023, we get 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 955

On to step 6:
955 goes into 686 0 times with a remainder of 686.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Subtract 0 from 686 to get 686.
Fetch the next digit (2) from the dividend, attach it to 686 and continue: 6862 / 955

Going ahead to step 7:
When dividing 6862 by 955, we get 7 with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 4107.0
Subtracting 6685 from 6862 leaves us with 177.
Grab the next digit (9) from the dividend, add it to 177, then carry on: 1779 / 955

Step 8:
955 can be fit into 1779 1 times, resulting in a remainder of 824.
Record the quotient 1 as the next digit in the result. 
Result so far: 41071.0
If we subtract 955 from 1779, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Advancing to step 9:
8240 divided by 955 is 8 with a remainder of 600.
The number 8 becomes the next digit in our result. 
Result so far: 41071.8
If we take 7640 away from 8240, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
955 goes into 6000 6 times with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 41071.86
Subtract 5730 from 6000 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 11:
955 can be fit into 2700 2 times, resulting in a remainder of 790.
Use 2 as the next digit of our solution. 
Result so far: 41071.862
If we take 1910 away from 2700, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 12:
If we divide 7900 by 955, we get 8 and a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 41071.8628
If we take 7640 away from 7900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
When dividing 2600 by 955, we get 2 with a remainder of 690.
The next digit of our result is 2. 
Result so far: 41071.86282
If we subtract 1910 from 2600, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 14:
When dividing 6900 by 955, we get 7 with a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 41071.862827
If we take 6685 away from 6900, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 15:
955 can be fit into 2150 2 times, resulting in a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 41071.8628272
If we take 1910 away from 2150, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
If we divide 2400 by 955, we get 2 and a remainder of 490.
The next digit of our result is 2. 
Result so far: 41071.86282722
Subtract 1910 from 2400 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 41071.86282722 with a balance of 4.9e-07.
