We divide 54246017 by 129
Our goal is to divide 54246017 by 129.

Step 1:
5 divided by 129 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 129

On to step 2:
54 divided by 129 is 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 129

Advancing to step 3:
129 goes into 542 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 516 from 542 to get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 129

Advancing to step 4:
If we divide 264 by 129, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 258 from 264 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 129

Going ahead to step 5:
129 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 129

Step 6:
660 divided by 129 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4205.0
Deduct 645 from 660 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 129

Let's proceed to step 7:
129 can be fit into 151 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 42051.0
Subtracting 129 from 151 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 129

Moving on to step 8:
The number 129 fits into 227 1 times, leaving a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 420511.0
Subtract 129 from 227 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
When dividing 980 by 129, we get 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 420511.7
Deduct 903 from 980 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 10:
The number 129 fits into 770 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 420511.75
Deduct 645 from 770 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
If we divide 1250 by 129, we get 9 and a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 420511.759
The remainder is 89 after subtracting 1161 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 12:
890 divided by 129 is 6 with a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 420511.7596
Deduct 774 from 890 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 13:
If we divide 1160 by 129, we get 8 and a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 420511.75968
Deduct 1032 from 1160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
If we divide 1280 by 129, we get 9 and a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 420511.759689
The remainder is 119 after subtracting 1161 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 15:
When dividing 1190 by 129, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 420511.7596899
The remainder is 29 after subtracting 1161 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 420511.7596899 with a remainder of 2.9e-07.
