12122718 ÷ 446 
We're looking to find how many times 446 goes into 12122718.

Advancing to step 1:
If we divide 1 by 446, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 446

On to step 2:
446 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 446

Let's proceed to step 3:
446 can be fit into 121 0 times, resulting in a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 446

Let's proceed to step 4:
1212 divided by 446 is 2 with a remainder of 320.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 892 from 1212 and we're left with 320.
Grab the next digit (2) from the dividend, add it to 320, then carry on: 3202 / 446

Advancing to step 5:
If we divide 3202 by 446, we get 7 and a remainder of 80.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 3122 away from 3202, we end up with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 446

Advancing to step 6:
446 goes into 807 1 times with a remainder of 361.
Put 1 as the next digit of the answer. 
Result so far: 271.0
Subtracting 446 from 807 leaves us with 361.
Grab the next digit (1) from the dividend, add it to 361, then carry on: 3611 / 446

Step 7:
If we divide 3611 by 446, we get 8 and a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 2718.0
If we take 3568 away from 3611, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 446

Going ahead to step 8:
If we divide 438 by 446, we get 0 and a remainder of 438.
Record the quotient 0 as the next digit in the result. 
Result so far: 27180.0
Deduct 0 from 438 and we're left 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 9:
446 can be fit into 4380 9 times, resulting in a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 27180.9
The remainder is 366 after subtracting 4014 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 10:
When dividing 3660 by 446, we get 8 with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 27180.98
The remainder is 92 after subtracting 3568 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
920 divided by 446 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 27180.982
Subtract 892 from 920 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 446 fits into 280 0 times, leaving a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 27180.982
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
446 goes into 2800 6 times with a remainder of 124.
The next digit of our result is 6. 
Result so far: 27180.98206
Deduct 2676 from 2800 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
If we divide 1240 by 446, we get 2 and a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 27180.982062
If we take 892 away from 1240, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 15:
If we divide 3480 by 446, we get 7 and a remainder of 358.
The number 7 becomes the next digit in our result. 
Result so far: 27180.9820627
If we take 3122 away from 3480, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 16:
If we divide 3580 by 446, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 27180.98206278
If we take 3568 away from 3580, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 27180.98206278 and a remainder of 1.2e-08.
