4367987 ÷ 405 
We want to divide 4367987 by 405.

Advancing 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
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 405

Step 2:
When dividing 43 by 405, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 405

Advancing to step 3:
436 divided by 405 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 405 away from 436, we end up with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 405

On to step 4:
405 goes into 317 0 times with a remainder of 317.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 317 leaves us with 317.
Take the next digit (9) from the dividend and append it to 317, then repeat: 3179 / 405

Let's proceed to step 5:
The number 405 fits into 3179 7 times, leaving a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 2835 away from 3179, we end up with 344.
Take the next digit (8) from the dividend and append it to 344, then repeat: 3448 / 405

On to step 6:
405 can be fit into 3448 8 times, resulting in a remainder of 208.
The next digit of our result is 8. 
Result so far: 1078.0
Deduct 3240 from 3448 and we're left with 208.
Take the next digit (7) from the dividend and append it to 208, then repeat: 2087 / 405

Moving on to step 7:
The number 405 fits into 2087 5 times, leaving a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 10785.0
If we take 2025 away from 2087, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
405 goes into 620 1 times with a remainder of 215.
The next digit of our result is 1. 
Result so far: 10785.1
Subtract 405 from 620 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 9:
If we divide 2150 by 405, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 10785.15
The remainder is 125 after subtracting 2025 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 10:
If we divide 1250 by 405, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 10785.153
If we take 1215 away from 1250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
The number 405 fits into 350 0 times, leaving a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 10785.153
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
405 goes into 3500 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 10785.15308
Subtracting 3240 from 3500 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
When dividing 2600 by 405, we get 6 with a remainder of 170.
The number 6 becomes the next digit in our result. 
Result so far: 10785.153086
The remainder is 170 after subtracting 2430 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
If we divide 1700 by 405, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 10785.1530864
Deduct 1620 from 1700 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
When dividing 800 by 405, we get 1 with a remainder of 395.
Write down 1 as next digit of the result. 
Result so far: 10785.15308641
If we subtract 405 from 800, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

In conclusion, the division gives 10785.15308641 with a balance of 3.95e-07.
