We divide 18691207 by 129
We want to divide 18691207 by 129.

Moving on to step 1:
129 goes into 1 0 times 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.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 129

Let's proceed to step 2:
18 divided by 129 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 129

Moving on to step 3:
186 divided by 129 is 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 129 from 186, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 129

Going ahead to step 4:
When dividing 579 by 129, we get 4 with a remainder of 63.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 516 from 579 leaves us with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 129

Let's proceed to step 5:
631 divided by 129 is 4 with a remainder of 115.
The next digit of our result is 4. 
Result so far: 144.0
Subtract 516 from 631 to get 115.
Append the next digit (2) from the dividend to 115 and continue with: 1152 / 129

Going ahead to step 6:
1152 divided by 129 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 1448.0
If we subtract 1032 from 1152, we get 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 129

Advancing to step 7:
When dividing 1200 by 129, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 14489.0
Deduct 1161 from 1200 and we're left with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 129

Advancing to step 8:
129 goes into 397 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 144893.0
If we subtract 387 from 397, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
129 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 144893.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
129 can be fit into 1000 7 times, resulting in a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 144893.07
Subtract 903 from 1000 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 11:
The number 129 fits into 970 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 144893.077
Subtracting 903 from 970 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 144893.077 with a remaining 0.0067.
