Let's divide 63689015 by 405
We're looking to find how many times 405 goes into 63689015.

Let's proceed to step 1:
405 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 405

On to step 2:
The number 405 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 405

Moving on to step 3:
405 goes into 636 1 times with a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 231 after subtracting 405 from 636.
Take the next digit (8) from the dividend and append it to 231, then repeat: 2318 / 405

Step 4:
2318 divided by 405 is 5 with a remainder of 293.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2025 away from 2318, we end up with 293.
Fetch the next digit (9) from the dividend, attach it to 293 and continue: 2939 / 405

Moving on to step 5:
If we divide 2939 by 405, we get 7 and a remainder of 104.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we take 2835 away from 2939, we end up with 104.
Append the next digit (0) from the dividend to 104 and continue with: 1040 / 405

On to step 6:
1040 divided by 405 is 2 with a remainder of 230.
The next digit of our result is 2. 
Result so far: 1572.0
If we take 810 away from 1040, we end up with 230.
Grab the next digit (1) from the dividend, add it to 230, then carry on: 2301 / 405

Advancing to step 7:
If we divide 2301 by 405, we get 5 and a remainder of 276.
Use 5 as the next digit of our solution. 
Result so far: 15725.0
Deduct 2025 from 2301 and we're left with 276.
Append the next digit (5) from the dividend to 276 and continue with: 2765 / 405

Let's proceed to step 8:
When dividing 2765 by 405, we get 6 with a remainder of 335.
The number 6 becomes the next digit in our result. 
Result so far: 157256.0
Deduct 2430 from 2765 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 9:
3350 divided by 405 is 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 157256.8
Subtracting 3240 from 3350 leaves us 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.

Moving on to step 10:
405 can be fit into 1100 2 times, resulting in a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 157256.82
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.

Moving on to step 11:
405 goes into 2900 7 times with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 157256.827
The remainder is 65 after subtracting 2835 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
If we divide 650 by 405, we get 1 and a remainder of 245.
Put 1 as the next digit of the answer. 
Result so far: 157256.8271
Subtracting 405 from 650 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.

Step 13:
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: 157256.82716
If we subtract 2430 from 2450, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 405 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 157256.82716
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
405 can be fit into 2000 4 times, resulting in a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 157256.8271604
If we subtract 1620 from 2000, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 16:
405 goes into 3800 9 times with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 157256.82716049
The remainder is 155 after subtracting 3645 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 157256.82716049, with a leftover of 1.55e-07.
