12433511 ÷ 102 
Our goal is to divide 12433511 by 102.

Let's proceed to step 1:
When dividing 1 by 102, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
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 / 102

Moving on to step 2:
102 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 102

Moving on to step 3:
If we divide 124 by 102, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 102 from 124 and we're left with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 102

Advancing to step 4:
When dividing 223 by 102, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 204 from 223 to get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 102

Advancing to step 5:
If we divide 193 by 102, we get 1 and a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 102 from 193 and we're left with 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 102

Advancing to step 6:
102 goes into 915 8 times with a remainder of 99.
The number 8 becomes the next digit in our result. 
Result so far: 1218.0
Deduct 816 from 915 and we're left with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 102

Let's proceed to step 7:
102 can be fit into 991 9 times, resulting in a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 12189.0
Subtracting 918 from 991 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 102

Moving on to step 8:
If we divide 731 by 102, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 121897.0
Subtract 714 from 731 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 102 fits into 170 1 times, leaving a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 121897.1
If we take 102 away from 170, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
If we divide 680 by 102, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 121897.16
If we take 612 away from 680, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
If we divide 680 by 102, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 121897.166
Subtracting 612 from 680 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 121897.166 and a remainder of 0.0068.
