12154686 ÷ 164 
Our goal is to divide 12154686 by 164.

Going ahead to step 1:
164 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 164

Moving on to step 2:
164 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 164

Advancing to step 3:
The number 164 fits into 121 0 times, leaving a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Bring next digit (5) of the dividend behind the 121 and repeat the process: 1215 / 164

Let's proceed to step 4:
164 can be fit into 1215 7 times, resulting in a remainder of 67.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 67 after subtracting 1148 from 1215.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 164

Going ahead to step 5:
164 can be fit into 674 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 656 from 674 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 164

Advancing to step 6:
186 divided by 164 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
Subtract 164 from 186 to get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 164

Advancing to step 7:
When dividing 228 by 164, we get 1 with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 7411.0
Subtract 164 from 228 to get 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 164

Moving on to step 8:
164 goes into 646 3 times with a remainder of 154.
Write down 3 as next digit of the result. 
Result so far: 74113.0
If we take 492 away from 646, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
1540 divided by 164 is 9 with a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 74113.9
Deduct 1476 from 1540 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
The number 164 fits into 640 3 times, leaving a remainder of 148.
The next digit of our result is 3. 
Result so far: 74113.93
If we take 492 away from 640, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
164 goes into 1480 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 74113.939
Subtracting 1476 from 1480 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 164 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 74113.939
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
The number 164 fits into 400 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 74113.93902
If we take 328 away from 400, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
164 can be fit into 720 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 74113.939024
If we subtract 656 from 720, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
If we divide 640 by 164, we get 3 and a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 74113.9390243
If we take 492 away from 640, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 16:
If we divide 1480 by 164, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 74113.93902439
Subtract 1476 from 1480 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 74113.93902439, and the remainder is 4e-09.
