154623 divided by 31 
We want to figure out the number of times 154623 can be divided by 31.

Going ahead to step 1:
If we divide 1 by 31, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 31

Step 2:
31 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 31

On to step 3:
154 divided by 31 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 124 from 154 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 31

On to step 4:
If we divide 306 by 31, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 279 from 306 and we're left with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 31

Going ahead to step 5:
The number 31 fits into 272 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 498.0
If we take 248 away from 272, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 31

Going ahead to step 6:
If we divide 243 by 31, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 4987.0
Subtract 217 from 243 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
31 can be fit into 260 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4987.8
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 31, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 4987.83
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
When dividing 270 by 31, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 4987.838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
31 can be fit into 220 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4987.8387
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4987.8387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
31 can be fit into 300 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 4987.838709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
The number 31 fits into 210 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 4987.8387096
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 31, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 4987.83870967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 4987.83870967, with a leftover of 2.3e-08.
