Let's divide 54980486 by 431
We're looking to find how many times 431 goes into 54980486.

Moving on to step 1:
431 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 431

Going ahead to step 2:
431 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 431

Advancing to step 3:
The number 431 fits into 549 1 times, leaving a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 431 from 549 leaves us with 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 431

Step 4:
If we divide 1188 by 431, we get 2 and a remainder of 326.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 862 from 1188, we get 326.
Grab the next digit (0) from the dividend, add it to 326, then carry on: 3260 / 431

Moving on to step 5:
431 can be fit into 3260 7 times, resulting in a remainder of 243.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtracting 3017 from 3260 leaves us with 243.
Append the next digit (4) from the dividend to 243 and continue with: 2434 / 431

Moving on to step 6:
431 can be fit into 2434 5 times, resulting in a remainder of 279.
Use 5 as the next digit of our solution. 
Result so far: 1275.0
If we subtract 2155 from 2434, we get 279.
Include the next digit (8) from the dividend after 279, then repeat: 2798 / 431

Moving on to step 7:
If we divide 2798 by 431, we get 6 and a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 12756.0
If we subtract 2586 from 2798, we get 212.
Take the next digit (6) from the dividend and append it to 212, then repeat: 2126 / 431

Step 8:
2126 divided by 431 is 4 with a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 127564.0
Subtracting 1724 from 2126 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
If we divide 4020 by 431, we get 9 and a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 127564.9
Deduct 3879 from 4020 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 10:
431 can be fit into 1410 3 times, resulting in a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 127564.93
Deduct 1293 from 1410 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 11:
1170 divided by 431 is 2 with a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 127564.932
Subtracting 862 from 1170 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
The number 431 fits into 3080 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 127564.9327
Subtract 3017 from 3080 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 13:
431 goes into 630 1 times with a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 127564.93271
Subtract 431 from 630 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 14:
1990 divided by 431 is 4 with a remainder of 266.
The number 4 becomes the next digit in our result. 
Result so far: 127564.932714
Subtract 1724 from 1990 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 15:
If we divide 2660 by 431, we get 6 and a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 127564.9327146
If we subtract 2586 from 2660, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 16:
If we divide 740 by 431, we get 1 and a remainder of 309.
The next digit of our result is 1. 
Result so far: 127564.93271461
Subtract 431 from 740 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

The final result is 127564.93271461 with a remainder of 3.09e-07.
