35389960 divided by 419 
The aim is to understand the frequency of 419 in 35389960.

Moving on to step 1:
If we divide 3 by 419, we get 0 and 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.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 419

On to step 2:
If we divide 35 by 419, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 419

Going ahead to step 3:
419 can be fit into 353 0 times, resulting in a remainder of 353.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 353, we get 353.
Take the next digit (8) from the dividend and append it to 353, then repeat: 3538 / 419

Going ahead to step 4:
3538 divided by 419 is 8 with a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 3352 from 3538, we get 186.
Grab the next digit (9) from the dividend, add it to 186, then carry on: 1869 / 419

Moving on to step 5:
When dividing 1869 by 419, we get 4 with a remainder of 193.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 1676 from 1869 and we're left with 193.
Bring next digit (9) of the dividend behind the 193 and repeat the process: 1939 / 419

Let's proceed to step 6:
419 can be fit into 1939 4 times, resulting in a remainder of 263.
The next digit of our result is 4. 
Result so far: 844.0
If we subtract 1676 from 1939, we get 263.
Include the next digit (6) from the dividend after 263, then repeat: 2636 / 419

Advancing to step 7:
419 goes into 2636 6 times with a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 8446.0
Subtract 2514 from 2636 to get 122.
Take the next digit (0) from the dividend and append it to 122, then repeat: 1220 / 419

Let's proceed to step 8:
The number 419 fits into 1220 2 times, leaving a remainder of 382.
Use 2 as the next digit of our solution. 
Result so far: 84462.0
Subtracting 838 from 1220 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 9:
3820 divided by 419 is 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 84462.9
Subtracting 3771 from 3820 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
If we divide 490 by 419, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 84462.91
Subtract 419 from 490 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
419 can be fit into 710 1 times, resulting in a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 84462.911
If we subtract 419 from 710, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

After the division, we end up with 84462.911 and a remainder of 0.0291.
