Let's divide 12236394 by 187
Our goal is to divide 12236394 by 187.

Let's proceed to step 1:
The number 187 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 187

Advancing to step 2:
If we divide 12 by 187, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 187

On to step 3:
When dividing 122 by 187, we get 0 with a remainder of 122.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Bring next digit (3) of the dividend behind the 122 and repeat the process: 1223 / 187

Advancing to step 4:
187 can be fit into 1223 6 times, resulting in a remainder of 101.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 1122 from 1223 leaves us with 101.
Fetch the next digit (6) from the dividend, attach it to 101 and continue: 1016 / 187

Moving on to step 5:
187 goes into 1016 5 times with a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 81 after subtracting 935 from 1016.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 187

Advancing to step 6:
187 can be fit into 813 4 times, resulting in a remainder of 65.
The next digit of our result is 4. 
Result so far: 654.0
Deduct 748 from 813 and we're left with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 187

Step 7:
When dividing 659 by 187, we get 3 with a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 6543.0
If we take 561 away from 659, we end up with 98.
Bring next digit (4) of the dividend behind the 98 and repeat the process: 984 / 187

Advancing to step 8:
187 can be fit into 984 5 times, resulting in a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 65435.0
If we take 935 away from 984, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
The number 187 fits into 490 2 times, leaving a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 65435.2
Deduct 374 from 490 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
187 goes into 1160 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 65435.26
Deduct 1122 from 1160 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 187, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 65435.262
Subtract 374 from 380 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
60 divided by 187 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 65435.262
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
If we divide 600 by 187, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 65435.26203
The remainder is 39 after subtracting 561 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
If we divide 390 by 187, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 65435.262032
If we subtract 374 from 390, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
187 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 65435.262032
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
1600 divided by 187 is 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 65435.26203208
Subtracting 1496 from 1600 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 65435.26203208 and a remainder of 1.04e-07.
