12216232 ÷ 158 
We're looking to find how many times 158 goes into 12216232.

Moving on to step 1:
1 divided by 158 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 158

Advancing to step 2:
If we divide 12 by 158, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 158

On to step 3:
122 divided by 158 is 0 with a remainder of 122.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Fetch the next digit (1) from the dividend, attach it to 122 and continue: 1221 / 158

Going ahead to step 4:
1221 divided by 158 is 7 with a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 1106 from 1221 to get 115.
Fetch the next digit (6) from the dividend, attach it to 115 and continue: 1156 / 158

Advancing to step 5:
The number 158 fits into 1156 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 1106 from 1156 and we're left with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 158

Going ahead to step 6:
502 divided by 158 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 773.0
If we take 474 away from 502, we end up with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 158

Going ahead to step 7:
The number 158 fits into 283 1 times, leaving a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 7731.0
Deduct 158 from 283 and we're left with 125.
Grab the next digit (2) from the dividend, add it to 125, then carry on: 1252 / 158

On to step 8:
When dividing 1252 by 158, we get 7 with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 77317.0
Subtracting 1106 from 1252 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
If we divide 1460 by 158, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 77317.9
If we take 1422 away from 1460, we end up 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.

On to step 10:
158 goes into 380 2 times with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 77317.92
Subtract 316 from 380 to 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.

Advancing to step 11:
640 divided by 158 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 77317.924
If we subtract 632 from 640, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
80 divided by 158 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 77317.924
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 158 fits into 800 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 77317.92405
Deduct 790 from 800 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
When dividing 100 by 158, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 77317.92405
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
When dividing 1000 by 158, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 77317.9240506
The remainder is 52 after subtracting 948 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 16:
158 can be fit into 520 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 77317.92405063
The remainder is 46 after subtracting 474 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 77317.92405063 and a remainder of 4.6e-08.
