9966684 ÷ 418 
Our goal is to divide 9966684 by 418.

Advancing to step 1:
The number 418 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 418

Step 2:
418 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 418

Moving on to step 3:
When dividing 996 by 418, we get 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 836 from 996 to get 160.
Bring next digit (6) of the dividend behind the 160 and repeat the process: 1606 / 418

On to step 4:
If we divide 1606 by 418, we get 3 and a remainder of 352.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 1254 from 1606 to get 352.
Bring next digit (6) of the dividend behind the 352 and repeat the process: 3526 / 418

Advancing to step 5:
When dividing 3526 by 418, we get 8 with a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 238.0
If we subtract 3344 from 3526, we get 182.
Include the next digit (8) from the dividend after 182, then repeat: 1828 / 418

Let's proceed to step 6:
When dividing 1828 by 418, we get 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 2384.0
Subtract 1672 from 1828 to get 156.
Include the next digit (4) from the dividend after 156, then repeat: 1564 / 418

Let's proceed to step 7:
When dividing 1564 by 418, we get 3 with a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 23843.0
The remainder is 310 after subtracting 1254 from 1564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 8:
If we divide 3100 by 418, we get 7 and a remainder of 174.
Put 7 as the next digit of the answer. 
Result so far: 23843.7
If we subtract 2926 from 3100, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
If we divide 1740 by 418, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 23843.74
Deduct 1672 from 1740 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 418 is 1 with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 23843.741
If we subtract 418 from 680, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 11:
If we divide 2620 by 418, we get 6 and a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 23843.7416
Deduct 2508 from 2620 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
418 can be fit into 1120 2 times, resulting in a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 23843.74162
Subtracting 836 from 1120 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
2840 divided by 418 is 6 with a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 23843.741626
Subtract 2508 from 2840 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 14:
418 goes into 3320 7 times with a remainder of 394.
The next digit of our result is 7. 
Result so far: 23843.7416267
If we subtract 2926 from 3320, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 15:
The number 418 fits into 3940 9 times, leaving a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 23843.74162679
If we take 3762 away from 3940, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 23843.74162679, with a leftover of 1.78e-07.
