We're dividing 69411841 by 129 
We want to divide 69411841 by 129.

On to step 1:
6 divided by 129 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 129

Moving on to step 2:
129 goes into 69 0 times with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 129

Let's proceed to step 3:
The number 129 fits into 694 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 5.0
If we take 645 away from 694, we end up with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 129

Advancing to step 4:
If we divide 491 by 129, we get 3 and a remainder of 104.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 387 from 491, we get 104.
Bring next digit (1) of the dividend behind the 104 and repeat the process: 1041 / 129

Let's proceed to step 5:
129 goes into 1041 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 538.0
Subtract 1032 from 1041 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 129

Going ahead to step 6:
129 goes into 98 0 times with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 5380.0
Subtracting 0 from 98 leaves us with 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 129

Moving on to step 7:
129 can be fit into 984 7 times, resulting in a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 53807.0
Deduct 903 from 984 and we're left with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 129

Advancing to step 8:
When dividing 811 by 129, we get 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 538076.0
Deduct 774 from 811 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
The number 129 fits into 370 2 times, leaving a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 538076.2
Subtracting 258 from 370 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
If we divide 1120 by 129, we get 8 and a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 538076.28
Subtracting 1032 from 1120 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
129 goes into 880 6 times with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 538076.286
Subtracting 774 from 880 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 12:
The number 129 fits into 1060 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 538076.2868
Subtract 1032 from 1060 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
When dividing 280 by 129, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 538076.28682
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
129 goes into 220 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 538076.286821
If we take 129 away from 220, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 15:
The number 129 fits into 910 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 538076.2868217
The remainder is 7 after subtracting 903 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 16:
129 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 538076.2868217
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 538076.2868217 with a remaining 7e-08.
