3370130 divided by 406 
The aim is to understand the frequency of 406 in 3370130.

Step 1:
406 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 406

Moving on to step 2:
When dividing 33 by 406, we get 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 406

Moving on to step 3:
406 goes into 337 0 times with a remainder of 337.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 337, we end up with 337.
Include the next digit (0) from the dividend after 337, then repeat: 3370 / 406

On to step 4:
When dividing 3370 by 406, we get 8 with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 3248 from 3370 to get 122.
Include the next digit (1) from the dividend after 122, then repeat: 1221 / 406

Moving on to step 5:
1221 divided by 406 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 83.0
The remainder is 3 after subtracting 1218 from 1221.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 406

Going ahead to step 6:
406 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 830.0
If we subtract 0 from 33, we get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 406

Let's proceed to step 7:
The number 406 fits into 330 0 times, leaving a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 8300.0
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 8:
The number 406 fits into 3300 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8300.8
Deduct 3248 from 3300 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
520 divided by 406 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 8300.81
If we take 406 away from 520, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
If we divide 1140 by 406, we get 2 and a remainder of 328.
Write down 2 as next digit of the result. 
Result so far: 8300.812
Subtracting 812 from 1140 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 11:
If we divide 3280 by 406, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 8300.8128
Subtracting 3248 from 3280 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 406 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 8300.8128
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
3200 divided by 406 is 7 with a remainder of 358.
The next digit of our result is 7. 
Result so far: 8300.812807
Deduct 2842 from 3200 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 14:
When dividing 3580 by 406, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 8300.8128078
If we subtract 3248 from 3580, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 15:
3320 divided by 406 is 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8300.81280788
If we subtract 3248 from 3320, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 8300.81280788, and the remainder is 7.2e-08.
