74509687 ÷ 409 
Our goal is to divide 74509687 by 409.

Let's proceed to step 1:
409 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 409

Advancing to step 2:
The number 409 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 409

Moving on to step 3:
409 can be fit into 745 1 times, resulting in a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 409 away from 745, we end up with 336.
Fetch the next digit (0) from the dividend, attach it to 336 and continue: 3360 / 409

Moving on to step 4:
If we divide 3360 by 409, we get 8 and a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 3272 from 3360 to get 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 409

Going ahead to step 5:
If we divide 889 by 409, we get 2 and a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtracting 818 from 889 leaves us with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 409

Going ahead to step 6:
If we divide 716 by 409, we get 1 and a remainder of 307.
Use 1 as the next digit of our solution. 
Result so far: 1821.0
If we subtract 409 from 716, we get 307.
Fetch the next digit (8) from the dividend, attach it to 307 and continue: 3078 / 409

Moving on to step 7:
If we divide 3078 by 409, we get 7 and a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 18217.0
If we subtract 2863 from 3078, we get 215.
Bring next digit (7) of the dividend behind the 215 and repeat the process: 2157 / 409

Moving on to step 8:
409 goes into 2157 5 times with a remainder of 112.
Record the quotient 5 as the next digit in the result. 
Result so far: 182175.0
Subtracting 2045 from 2157 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
If we divide 1120 by 409, we get 2 and a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 182175.2
Subtracting 818 from 1120 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 10:
409 can be fit into 3020 7 times, resulting in a remainder of 157.
The next digit of our result is 7. 
Result so far: 182175.27
If we take 2863 away from 3020, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 11:
The number 409 fits into 1570 3 times, leaving a remainder of 343.
The next digit of our result is 3. 
Result so far: 182175.273
If we take 1227 away from 1570, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 12:
The number 409 fits into 3430 8 times, leaving a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 182175.2738
Subtracting 3272 from 3430 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 13:
409 goes into 1580 3 times with a remainder of 353.
The number 3 becomes the next digit in our result. 
Result so far: 182175.27383
Subtract 1227 from 1580 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 14:
409 can be fit into 3530 8 times, resulting in a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 182175.273838
Subtracting 3272 from 3530 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 15:
2580 divided by 409 is 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 182175.2738386
If we subtract 2454 from 2580, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 16:
409 can be fit into 1260 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 182175.27383863
If we take 1227 away from 1260, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 182175.27383863 with a remaining 3.3e-08.
