10420503 ÷ 418 
Let's see how many times 418 fits into 10420503.

Moving on to step 1:
418 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 418

Going ahead to step 2:
418 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 418

Moving on to step 3:
If we divide 104 by 418, we get 0 and a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 104 to get 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 418

Moving on to step 4:
If we divide 1042 by 418, we get 2 and a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 206 after subtracting 836 from 1042.
Fetch the next digit (0) from the dividend, attach it to 206 and continue: 2060 / 418

Step 5:
If we divide 2060 by 418, we get 4 and a remainder of 388.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 388 after subtracting 1672 from 2060.
Include the next digit (5) from the dividend after 388, then repeat: 3885 / 418

Going ahead to step 6:
3885 divided by 418 is 9 with a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 249.0
If we take 3762 away from 3885, we end up with 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 418

On to step 7:
1230 divided by 418 is 2 with a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 2492.0
Subtract 836 from 1230 to get 394.
Include the next digit (3) from the dividend after 394, then repeat: 3943 / 418

Advancing to step 8:
The number 418 fits into 3943 9 times, leaving a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 24929.0
Subtract 3762 from 3943 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 9:
1810 divided by 418 is 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 24929.4
Deduct 1672 from 1810 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
If we divide 1380 by 418, we get 3 and a remainder of 126.
The next digit of our result is 3. 
Result so far: 24929.43
If we take 1254 away from 1380, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
418 goes into 1260 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 24929.433
Subtracting 1254 from 1260 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 24929.433, with a leftover of 0.0006.
