54431984 ÷ 127 
Let's see how many times 127 fits into 54431984.

On to step 1:
127 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 127

On to step 2:
The number 127 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 127

Advancing to step 3:
127 goes into 544 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 508 from 544 leaves us with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 127

Step 4:
127 can be fit into 363 2 times, resulting in a remainder of 109.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 254 from 363, we get 109.
Append the next digit (1) from the dividend to 109 and continue with: 1091 / 127

Step 5:
When dividing 1091 by 127, we get 8 with a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 428.0
Subtract 1016 from 1091 to get 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 127

Moving on to step 6:
127 goes into 759 5 times with a remainder of 124.
The number 5 becomes the next digit in our result. 
Result so far: 4285.0
If we subtract 635 from 759, we get 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 127

Moving on to step 7:
The number 127 fits into 1248 9 times, leaving a remainder of 105.
The next digit of our result is 9. 
Result so far: 42859.0
Subtract 1143 from 1248 to get 105.
Grab the next digit (4) from the dividend, add it to 105, then carry on: 1054 / 127

Advancing to step 8:
1054 divided by 127 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 428598.0
Subtracting 1016 from 1054 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 127, we get 2 and a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 428598.2
The remainder is 126 after subtracting 254 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 10:
1260 divided by 127 is 9 with a remainder of 117.
Record the quotient 9 as the next digit in the result. 
Result so far: 428598.29
If we subtract 1143 from 1260, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 11:
The number 127 fits into 1170 9 times, leaving a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 428598.299
If we subtract 1143 from 1170, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 428598.299 with a remaining 0.0027.
