59146938 ÷ 405 
The aim is to understand the frequency of 405 in 59146938.

Going ahead to step 1:
If we divide 5 by 405, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 405

Moving on to step 2:
The number 405 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 405

Let's proceed to step 3:
The number 405 fits into 591 1 times, leaving a remainder of 186.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 405 from 591 and we're left with 186.
Take the next digit (4) from the dividend and append it to 186, then repeat: 1864 / 405

Advancing to step 4:
If we divide 1864 by 405, we get 4 and a remainder of 244.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1620 away from 1864, we end up with 244.
Include the next digit (6) from the dividend after 244, then repeat: 2446 / 405

Going ahead to step 5:
405 can be fit into 2446 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Deduct 2430 from 2446 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 405

Going ahead to step 6:
If we divide 169 by 405, we get 0 and a remainder of 169.
The number 0 becomes the next digit in our result. 
Result so far: 1460.0
The remainder is 169 after subtracting 0 from 169.
Append the next digit (3) from the dividend to 169 and continue with: 1693 / 405

Advancing to step 7:
The number 405 fits into 1693 4 times, leaving a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 14604.0
Subtracting 1620 from 1693 leaves us with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 405

On to step 8:
738 divided by 405 is 1 with a remainder of 333.
Write down 1 as next digit of the result. 
Result so far: 146041.0
Subtracting 405 from 738 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 9:
The number 405 fits into 3330 8 times, leaving a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 146041.8
If we take 3240 away from 3330, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
When dividing 900 by 405, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 146041.82
The remainder is 90 after subtracting 810 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
When dividing 900 by 405, we get 2 with a remainder of 90.
The next digit of our result is 2. 
Result so far: 146041.822
Deduct 810 from 900 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 146041.822 and a remainder of 0.009.
