We're dividing 74289453 by 405 
We're looking to find how many times 405 goes into 74289453.

On to step 1:
If we divide 7 by 405, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 405

Advancing to step 2:
When dividing 74 by 405, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 405

Going ahead to step 3:
The number 405 fits into 742 1 times, leaving a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 405 from 742 leaves us with 337.
Take the next digit (8) from the dividend and append it to 337, then repeat: 3378 / 405

Step 4:
3378 divided by 405 is 8 with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3240 from 3378 leaves us with 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 405

Going ahead to step 5:
If we divide 1389 by 405, we get 3 and a remainder of 174.
Write down 3 as next digit of the result. 
Result so far: 183.0
Subtracting 1215 from 1389 leaves us with 174.
Include the next digit (4) from the dividend after 174, then repeat: 1744 / 405

Advancing to step 6:
When dividing 1744 by 405, we get 4 with a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 1834.0
Deduct 1620 from 1744 and we're left with 124.
Grab the next digit (5) from the dividend, add it to 124, then carry on: 1245 / 405

Let's proceed to step 7:
When dividing 1245 by 405, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 18343.0
Subtract 1215 from 1245 to get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 405

Step 8:
303 divided by 405 is 0 with a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 183430.0
Subtract 0 from 303 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 9:
When dividing 3030 by 405, we get 7 with a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 183430.7
Subtract 2835 from 3030 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 10:
405 goes into 1950 4 times with a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 183430.74
If we take 1620 away from 1950, 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.

Step 11:
405 can be fit into 3300 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 183430.748
If we subtract 3240 from 3300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
The number 405 fits into 600 1 times, leaving a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 183430.7481
Deduct 405 from 600 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 13:
405 goes into 1950 4 times with a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 183430.74814
If we subtract 1620 from 1950, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
3300 divided by 405 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 183430.748148
Deduct 3240 from 3300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
405 can be fit into 600 1 times, resulting in a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 183430.7481481
If we take 405 away from 600, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 16:
405 can be fit into 1950 4 times, resulting in a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 183430.74814814
Subtract 1620 from 1950 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 183430.74814814 with a remainder of 3.3e-07.
