We're dividing 7256214 by 408 
The aim is to understand the frequency of 408 in 7256214.

Moving on to step 1:
If we divide 7 by 408, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 408

Advancing to step 2:
If we divide 72 by 408, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 408

Advancing to step 3:
725 divided by 408 is 1 with a remainder of 317.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 408 from 725 leaves us with 317.
Fetch the next digit (6) from the dividend, attach it to 317 and continue: 3176 / 408

Advancing to step 4:
408 can be fit into 3176 7 times, resulting in a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 2856 from 3176 to get 320.
Grab the next digit (2) from the dividend, add it to 320, then carry on: 3202 / 408

On to step 5:
When dividing 3202 by 408, we get 7 with a remainder of 346.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we subtract 2856 from 3202, we get 346.
Take the next digit (1) from the dividend and append it to 346, then repeat: 3461 / 408

Let's proceed to step 6:
408 can be fit into 3461 8 times, resulting in a remainder of 197.
Write down 8 as next digit of the result. 
Result so far: 1778.0
If we subtract 3264 from 3461, we get 197.
Grab the next digit (4) from the dividend, add it to 197, then carry on: 1974 / 408

Advancing to step 7:
408 goes into 1974 4 times with a remainder of 342.
Put 4 as the next digit of the answer. 
Result so far: 17784.0
The remainder is 342 after subtracting 1632 from 1974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 8:
When dividing 3420 by 408, we get 8 with a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 17784.8
If we take 3264 away from 3420, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
408 goes into 1560 3 times with a remainder of 336.
Put 3 as the next digit of the answer. 
Result so far: 17784.83
Subtract 1224 from 1560 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 10:
3360 divided by 408 is 8 with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 17784.838
Subtracting 3264 from 3360 leaves us 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.

Moving on to step 11:
When dividing 960 by 408, we get 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 17784.8382
Deduct 816 from 960 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
The number 408 fits into 1440 3 times, leaving a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 17784.83823
If we take 1224 away from 1440, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 13:
The number 408 fits into 2160 5 times, leaving a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 17784.838235
Deduct 2040 from 2160 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
If we divide 1200 by 408, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 17784.8382352
If we subtract 816 from 1200, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 15:
408 can be fit into 3840 9 times, resulting in a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 17784.83823529
The remainder is 168 after subtracting 3672 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 17784.83823529, and the remainder is 1.68e-07.
