We look at the division of 95999970 by 409 
The aim is to understand the frequency of 409 in 95999970.

Let's proceed to step 1:
If we divide 9 by 409, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 409

Advancing to step 2:
409 can be fit into 95 0 times, resulting in a remainder of 95.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 95 leaves us with 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 409

Let's proceed to step 3:
When dividing 959 by 409, we get 2 with a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 818 from 959 to get 141.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 409

Moving on to step 4:
409 can be fit into 1419 3 times, resulting in a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 1227 away from 1419, we end up with 192.
Take the next digit (9) from the dividend and append it to 192, then repeat: 1929 / 409

Advancing to step 5:
The number 409 fits into 1929 4 times, leaving a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 234.0
If we take 1636 away from 1929, we end up with 293.
Grab the next digit (9) from the dividend, add it to 293, then carry on: 2939 / 409

Let's proceed to step 6:
2939 divided by 409 is 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 2347.0
If we subtract 2863 from 2939, we get 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 409

Step 7:
When dividing 767 by 409, we get 1 with a remainder of 358.
The next digit of our result is 1. 
Result so far: 23471.0
Subtract 409 from 767 to get 358.
Bring next digit (0) of the dividend behind the 358 and repeat the process: 3580 / 409

Let's proceed to step 8:
If we divide 3580 by 409, we get 8 and a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 234718.0
The remainder is 308 after subtracting 3272 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 9:
The number 409 fits into 3080 7 times, leaving a remainder of 217.
The next digit of our result is 7. 
Result so far: 234718.7
Subtract 2863 from 3080 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 10:
If we divide 2170 by 409, we get 5 and a remainder of 125.
The next digit of our result is 5. 
Result so far: 234718.75
Deduct 2045 from 2170 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 11:
409 goes into 1250 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 234718.753
Subtracting 1227 from 1250 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
If we divide 230 by 409, we get 0 and a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 234718.753
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
The number 409 fits into 2300 5 times, leaving a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 234718.75305
If we take 2045 away from 2300, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 14:
409 can be fit into 2550 6 times, resulting in a remainder of 96.
The next digit of our result is 6. 
Result so far: 234718.753056
Deduct 2454 from 2550 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
The number 409 fits into 960 2 times, leaving a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 234718.7530562
Deduct 818 from 960 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 16:
409 goes into 1420 3 times with a remainder of 193.
Write down 3 as next digit of the result. 
Result so far: 234718.75305623
Deduct 1227 from 1420 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Our division results in 234718.75305623 with a remaining 1.93e-07.
