54348259 ÷ 31 
Our goal is to divide 54348259 by 31.

On to step 1:
If we divide 5 by 31, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 31

Advancing to step 2:
When dividing 54 by 31, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 31 away from 54, we end up with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 31

Let's proceed to step 3:
The number 31 fits into 233 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 217 from 233 and we're left with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 31

Advancing to step 4:
31 can be fit into 164 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtracting 155 from 164 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 31

Let's proceed to step 5:
98 divided by 31 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1753.0
Subtracting 93 from 98 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 31

Let's proceed to step 6:
52 divided by 31 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 17531.0
The remainder is 21 after subtracting 31 from 52.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 31

Step 7:
The number 31 fits into 215 6 times, leaving a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 175316.0
Subtract 186 from 215 to get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 31

Going ahead to step 8:
299 divided by 31 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1753169.0
Deduct 279 from 299 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 31, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 1753169.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1753169.64
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 31, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1753169.645
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 31 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1753169.6451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1753169.64516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 31, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1753169.645161
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 15:
When dividing 90 by 31, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1753169.6451612
If we subtract 62 from 90, we 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.

Let's proceed to step 16:
When dividing 280 by 31, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1753169.64516129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 1753169.64516129, with a leftover of 1e-09.
