We're dividing 13535533 by 407 
The aim is to understand the frequency of 407 in 13535533.

Moving on to step 1:
If we divide 1 by 407, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 407

On to step 2:
407 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 407

Advancing to step 3:
407 goes into 135 0 times with a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 135 and we're left with 135.
Fetch the next digit (3) from the dividend, attach it to 135 and continue: 1353 / 407

Let's proceed to step 4:
When dividing 1353 by 407, we get 3 with a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1221 away from 1353, we end up with 132.
Bring next digit (5) of the dividend behind the 132 and repeat the process: 1325 / 407

Advancing to step 5:
1325 divided by 407 is 3 with a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 1221 away from 1325, we end up with 104.
Take the next digit (5) from the dividend and append it to 104, then repeat: 1045 / 407

Going ahead to step 6:
The number 407 fits into 1045 2 times, leaving a remainder of 231.
Write down 2 as next digit of the result. 
Result so far: 332.0
If we subtract 814 from 1045, we get 231.
Fetch the next digit (3) from the dividend, attach it to 231 and continue: 2313 / 407

Advancing to step 7:
The number 407 fits into 2313 5 times, leaving a remainder of 278.
Record the quotient 5 as the next digit in the result. 
Result so far: 3325.0
Subtracting 2035 from 2313 leaves us with 278.
Bring next digit (3) of the dividend behind the 278 and repeat the process: 2783 / 407

Moving on to step 8:
407 can be fit into 2783 6 times, resulting in a remainder of 341.
Record the quotient 6 as the next digit in the result. 
Result so far: 33256.0
Deduct 2442 from 2783 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 9:
If we divide 3410 by 407, we get 8 and a remainder of 154.
The next digit of our result is 8. 
Result so far: 33256.8
If we subtract 3256 from 3410, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
When dividing 1540 by 407, we get 3 with a remainder of 319.
The next digit of our result is 3. 
Result so far: 33256.83
Subtracting 1221 from 1540 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 11:
407 goes into 3190 7 times with a remainder of 341.
Use 7 as the next digit of our solution. 
Result so far: 33256.837
If we take 2849 away from 3190, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 12:
If we divide 3410 by 407, we get 8 and a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 33256.8378
Subtract 3256 from 3410 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 13:
If we divide 1540 by 407, we get 3 and a remainder of 319.
Put 3 as the next digit of the answer. 
Result so far: 33256.83783
Subtract 1221 from 1540 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 14:
If we divide 3190 by 407, we get 7 and a remainder of 341.
Use 7 as the next digit of our solution. 
Result so far: 33256.837837
If we take 2849 away from 3190, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 15:
If we divide 3410 by 407, we get 8 and a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 33256.8378378
Subtracting 3256 from 3410 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
407 can be fit into 1540 3 times, resulting in a remainder of 319.
The next digit of our result is 3. 
Result so far: 33256.83783783
If we subtract 1221 from 1540, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The quotient of the division is 33256.83783783, and the remainder is 3.19e-07.
