71220408 ÷ 418 
We're looking to find how many times 418 goes into 71220408.

Advancing to step 1:
The number 418 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 418

Moving on to step 2:
When dividing 71 by 418, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 418

Going ahead to step 3:
If we divide 712 by 418, we get 1 and a remainder of 294.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 418 from 712 leaves us with 294.
Append the next digit (2) from the dividend to 294 and continue with: 2942 / 418

Step 4:
The number 418 fits into 2942 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 2926 away from 2942, we end up with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 418

Let's proceed to step 5:
If we divide 160 by 418, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtract 0 from 160 to get 160.
Append the next digit (4) from the dividend to 160 and continue with: 1604 / 418

Moving on to step 6:
418 can be fit into 1604 3 times, resulting in a remainder of 350.
Write down 3 as next digit of the result. 
Result so far: 1703.0
If we subtract 1254 from 1604, we get 350.
Bring next digit (0) of the dividend behind the 350 and repeat the process: 3500 / 418

Going ahead to step 7:
When dividing 3500 by 418, we get 8 with a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 17038.0
If we take 3344 away from 3500, we end up with 156.
Fetch the next digit (8) from the dividend, attach it to 156 and continue: 1568 / 418

On to step 8:
If we divide 1568 by 418, we get 3 and a remainder of 314.
The next digit of our result is 3. 
Result so far: 170383.0
Deduct 1254 from 1568 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 9:
3140 divided by 418 is 7 with a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 170383.7
If we take 2926 away from 3140, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 10:
If we divide 2140 by 418, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 170383.75
If we take 2090 away from 2140, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
418 goes into 500 1 times with a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 170383.751
If we subtract 418 from 500, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
820 divided by 418 is 1 with a remainder of 402.
Record the quotient 1 as the next digit in the result. 
Result so far: 170383.7511
Deduct 418 from 820 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final outcome is 170383.7511, with a leftover of 0.00402.
