We're dividing 12177571 by 153 
We're looking to find how many times 153 goes into 12177571.

Moving on to step 1:
153 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 153

On to step 2:
12 divided by 153 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 153

Going ahead to step 3:
If we divide 121 by 153, we get 0 and a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 153

Step 4:
The number 153 fits into 1217 7 times, leaving a remainder of 146.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 1071 away from 1217, we end up with 146.
Include the next digit (7) from the dividend after 146, then repeat: 1467 / 153

On to step 5:
The number 153 fits into 1467 9 times, leaving a remainder of 90.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 1377 from 1467 and we're left with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 153

On to step 6:
When dividing 905 by 153, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 795.0
The remainder is 140 after subtracting 765 from 905.
Bring next digit (7) of the dividend behind the 140 and repeat the process: 1407 / 153

Going ahead to step 7:
When dividing 1407 by 153, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 7959.0
Deduct 1377 from 1407 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 153

Let's proceed to step 8:
If we divide 301 by 153, we get 1 and a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 79591.0
If we subtract 153 from 301, we get 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 9:
1480 divided by 153 is 9 with a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 79591.9
The remainder is 103 after subtracting 1377 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
If we divide 1030 by 153, we get 6 and a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 79591.96
Subtract 918 from 1030 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
153 goes into 1120 7 times with a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 79591.967
Subtract 1071 from 1120 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
490 divided by 153 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 79591.9673
Subtracting 459 from 490 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
If we divide 310 by 153, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 79591.96732
Subtract 306 from 310 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.

Advancing to step 14:
If we divide 40 by 153, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 79591.96732
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
The number 153 fits into 400 2 times, leaving a remainder of 94.
The next digit of our result is 2. 
Result so far: 79591.9673202
Subtracting 306 from 400 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 16:
If we divide 940 by 153, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 79591.96732026
The remainder is 22 after subtracting 918 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 79591.96732026, and the remainder is 2.2e-08.
