12186146 divided by 801 
We're looking to find how many times 801 goes into 12186146.

Moving on to step 1:
The number 801 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 801

On to step 2:
801 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 801

Moving on to step 3:
121 divided by 801 is 0 with a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Fetch the next digit (8) from the dividend, attach it to 121 and continue: 1218 / 801

Step 4:
When dividing 1218 by 801, we get 1 with a remainder of 417.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 801 from 1218, we get 417.
Fetch the next digit (6) from the dividend, attach it to 417 and continue: 4176 / 801

Moving on to step 5:
If we divide 4176 by 801, we get 5 and a remainder of 171.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 4005 away from 4176, we end up with 171.
Take the next digit (1) from the dividend and append it to 171, then repeat: 1711 / 801

On to step 6:
The number 801 fits into 1711 2 times, leaving a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtracting 1602 from 1711 leaves us with 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 801

Advancing to step 7:
801 can be fit into 1094 1 times, resulting in a remainder of 293.
Record the quotient 1 as the next digit in the result. 
Result so far: 1521.0
Subtracting 801 from 1094 leaves us with 293.
Take the next digit (6) from the dividend and append it to 293, then repeat: 2936 / 801

On to step 8:
801 can be fit into 2936 3 times, resulting in a remainder of 533.
The number 3 becomes the next digit in our result. 
Result so far: 15213.0
Subtracting 2403 from 2936 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 9:
The number 801 fits into 5330 6 times, leaving a remainder of 524.
Put 6 as the next digit of the answer. 
Result so far: 15213.6
Subtract 4806 from 5330 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 10:
801 goes into 5240 6 times with a remainder of 434.
The number 6 becomes the next digit in our result. 
Result so far: 15213.66
Subtracting 4806 from 5240 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

The final result is 15213.66 with a remainder of 0.434.
