We look at the division of 4205670 by 487 
We're looking to find how many times 487 goes into 4205670.

Going ahead to step 1:
487 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 487

Moving on to step 2:
487 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 487

Step 3:
487 can be fit into 420 0 times, resulting in a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Include the next digit (5) from the dividend after 420, then repeat: 4205 / 487

Let's proceed to step 4:
The number 487 fits into 4205 8 times, leaving a remainder of 309.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 3896 from 4205 and we're left with 309.
Bring next digit (6) of the dividend behind the 309 and repeat the process: 3096 / 487

Step 5:
487 goes into 3096 6 times with a remainder of 174.
The next digit of our result is 6. 
Result so far: 86.0
If we take 2922 away from 3096, we end up with 174.
Fetch the next digit (7) from the dividend, attach it to 174 and continue: 1747 / 487

On to step 6:
487 can be fit into 1747 3 times, resulting in a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 863.0
Subtract 1461 from 1747 to get 286.
Include the next digit (0) from the dividend after 286, then repeat: 2860 / 487

Advancing to step 7:
2860 divided by 487 is 5 with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 8635.0
Deduct 2435 from 2860 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 8:
If we divide 4250 by 487, we get 8 and a remainder of 354.
Write down 8 as next digit of the result. 
Result so far: 8635.8
Deduct 3896 from 4250 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 9:
When dividing 3540 by 487, we get 7 with a remainder of 131.
The next digit of our result is 7. 
Result so far: 8635.87
Deduct 3409 from 3540 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 10:
487 goes into 1310 2 times with a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 8635.872
Deduct 974 from 1310 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 11:
487 goes into 3360 6 times with a remainder of 438.
Write down 6 as next digit of the result. 
Result so far: 8635.8726
Subtracting 2922 from 3360 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 12:
487 goes into 4380 8 times with a remainder of 484.
Use 8 as the next digit of our solution. 
Result so far: 8635.87268
The remainder is 484 after subtracting 3896 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 13:
487 goes into 4840 9 times with a remainder of 457.
Put 9 as the next digit of the answer. 
Result so far: 8635.872689
Subtracting 4383 from 4840 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 14:
When dividing 4570 by 487, we get 9 with a remainder of 187.
The next digit of our result is 9. 
Result so far: 8635.8726899
If we subtract 4383 from 4570, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final result is 8635.8726899 with a remainder of 1.87e-06.
