43749704 ÷ 405 
We want to figure out the number of times 43749704 can be divided by 405.

Let's proceed to step 1:
405 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 405

Going ahead to step 2:
43 divided by 405 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 405

Going ahead to step 3:
If we divide 437 by 405, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 405 away from 437, we end up with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 405

Going ahead to step 4:
The number 405 fits into 324 0 times, leaving a remainder of 324.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 324, we get 324.
Grab the next digit (9) from the dividend, add it to 324, then carry on: 3249 / 405

Let's proceed to step 5:
If we divide 3249 by 405, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 3240 from 3249, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 405

Going ahead to step 6:
97 divided by 405 is 0 with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 1080.0
Subtracting 0 from 97 leaves us with 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 405

Let's proceed to step 7:
If we divide 970 by 405, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 10802.0
Deduct 810 from 970 and we're left with 160.
Include the next digit (4) from the dividend after 160, then repeat: 1604 / 405

Advancing to step 8:
1604 divided by 405 is 3 with a remainder of 389.
Put 3 as the next digit of the answer. 
Result so far: 108023.0
Subtract 1215 from 1604 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 9:
When dividing 3890 by 405, we get 9 with a remainder of 245.
Record the quotient 9 as the next digit in the result. 
Result so far: 108023.9
Subtracting 3645 from 3890 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 10:
When dividing 2450 by 405, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 108023.96
If we take 2430 away from 2450, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
405 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 108023.96
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
The number 405 fits into 2000 4 times, leaving a remainder of 380.
The next digit of our result is 4. 
Result so far: 108023.9604
The remainder is 380 after subtracting 1620 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
405 goes into 3800 9 times with a remainder of 155.
The number 9 becomes the next digit in our result. 
Result so far: 108023.96049
If we take 3645 away from 3800, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 14:
When dividing 1550 by 405, we get 3 with a remainder of 335.
Use 3 as the next digit of our solution. 
Result so far: 108023.960493
If we subtract 1215 from 1550, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 15:
3350 divided by 405 is 8 with a remainder of 110.
The next digit of our result is 8. 
Result so far: 108023.9604938
Deduct 3240 from 3350 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 16:
1100 divided by 405 is 2 with a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 108023.96049382
The remainder is 290 after subtracting 810 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Our division results in 108023.96049382 with a remaining 2.9e-07.
