We're dividing 43419901 by 487 
We want to figure out the number of times 43419901 can be divided by 487.

On to step 1:
When dividing 4 by 487, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 487

On to step 2:
487 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 487

On to step 3:
When dividing 434 by 487, we get 0 with a remainder of 434.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Take the next digit (1) from the dividend and append it to 434, then repeat: 4341 / 487

Advancing to step 4:
487 goes into 4341 8 times with a remainder of 445.
The next digit of our result is 8. 
Result so far: 8.0
If we take 3896 away from 4341, we end up with 445.
Grab the next digit (9) from the dividend, add it to 445, then carry on: 4459 / 487

Step 5:
If we divide 4459 by 487, we get 9 and a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 4383 from 4459 and we're left with 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 487

Going ahead to step 6:
If we divide 769 by 487, we get 1 and a remainder of 282.
The next digit of our result is 1. 
Result so far: 891.0
Subtract 487 from 769 to get 282.
Fetch the next digit (0) from the dividend, attach it to 282 and continue: 2820 / 487

On to step 7:
2820 divided by 487 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 8915.0
Deduct 2435 from 2820 and we're left with 385.
Include the next digit (1) from the dividend after 385, then repeat: 3851 / 487

Advancing to step 8:
When dividing 3851 by 487, we get 7 with a remainder of 442.
Record the quotient 7 as the next digit in the result. 
Result so far: 89157.0
If we subtract 3409 from 3851, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 9:
487 goes into 4420 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 89157.9
The remainder is 37 after subtracting 4383 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
370 divided by 487 is 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 89157.9
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 11:
487 can be fit into 3700 7 times, resulting in a remainder of 291.
Record the quotient 7 as the next digit in the result. 
Result so far: 89157.907
Subtract 3409 from 3700 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 12:
487 goes into 2910 5 times with a remainder of 475.
The next digit of our result is 5. 
Result so far: 89157.9075
The remainder is 475 after subtracting 2435 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 13:
The number 487 fits into 4750 9 times, leaving a remainder of 367.
Write down 9 as next digit of the result. 
Result so far: 89157.90759
Subtract 4383 from 4750 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 14:
When dividing 3670 by 487, we get 7 with a remainder of 261.
Use 7 as the next digit of our solution. 
Result so far: 89157.907597
Deduct 3409 from 3670 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 15:
2610 divided by 487 is 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 89157.9075975
If we subtract 2435 from 2610, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 16:
1750 divided by 487 is 3 with a remainder of 289.
The next digit of our result is 3. 
Result so far: 89157.90759753
Subtracting 1461 from 1750 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Our division results in 89157.90759753 with a remaining 2.89e-07.
