We divide 54614846 by 129
We want to divide 54614846 by 129.

On to step 1:
129 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 129

Going ahead to step 2:
If we divide 54 by 129, we get 0 and 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.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 129

On to step 3:
129 goes into 546 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 30 after subtracting 516 from 546.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 129

Let's proceed to step 4:
129 can be fit into 301 2 times, resulting in a remainder of 43.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 258 from 301 leaves us with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 129

Advancing to step 5:
If we divide 434 by 129, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
If we take 387 away from 434, we end up with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 129

Going ahead to step 6:
478 divided by 129 is 3 with a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 4233.0
Deduct 387 from 478 and we're left with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 129

On to step 7:
The number 129 fits into 914 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 42337.0
Subtract 903 from 914 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 129

Moving on to step 8:
The number 129 fits into 116 0 times, leaving a remainder of 116.
Record the quotient 0 as the next digit in the result. 
Result so far: 423370.0
The remainder is 116 after subtracting 0 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
The number 129 fits into 1160 8 times, leaving a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 423370.8
Subtracting 1032 from 1160 leaves us 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.

Moving on to step 10:
129 goes into 1280 9 times with a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 423370.89
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.

Moving on to step 11:
1190 divided by 129 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 423370.899
If we subtract 1161 from 1190, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 423370.899 with a remaining 0.0029.
