Let's divide 31615051 by 810
Our goal is to divide 31615051 by 810.

Moving on to step 1:
3 divided by 810 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 810

Step 2:
31 divided by 810 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 810

On to step 3:
316 divided by 810 is 0 with a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 810

Going ahead to step 4:
If we divide 3161 by 810, we get 3 and a remainder of 731.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2430 from 3161, we get 731.
Grab the next digit (5) from the dividend, add it to 731, then carry on: 7315 / 810

Moving on to step 5:
The number 810 fits into 7315 9 times, leaving a remainder of 25.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 7290 from 7315, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 810

Going ahead to step 6:
810 can be fit into 250 0 times, resulting in a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 390.0
Deduct 0 from 250 and we're left with 250.
Bring next digit (5) of the dividend behind the 250 and repeat the process: 2505 / 810

Advancing to step 7:
810 can be fit into 2505 3 times, resulting in a remainder of 75.
The next digit of our result is 3. 
Result so far: 3903.0
If we take 2430 away from 2505, we end up with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 810

Going ahead to step 8:
The number 810 fits into 751 0 times, leaving a remainder of 751.
Write down 0 as next digit of the result. 
Result so far: 39030.0
If we subtract 0 from 751, we get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Step 9:
810 goes into 7510 9 times with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 39030.9
If we take 7290 away from 7510, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
810 goes into 2200 2 times with a remainder of 580.
The number 2 becomes the next digit in our result. 
Result so far: 39030.92
The remainder is 580 after subtracting 1620 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 11:
When dividing 5800 by 810, we get 7 with a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 39030.927
Subtract 5670 from 5800 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
1300 divided by 810 is 1 with a remainder of 490.
Record the quotient 1 as the next digit in the result. 
Result so far: 39030.9271
Subtracting 810 from 1300 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
810 goes into 4900 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 39030.92716
Subtracting 4860 from 4900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
810 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 39030.92716
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
If we divide 4000 by 810, we get 4 and a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 39030.9271604
Deduct 3240 from 4000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 16:
If we divide 7600 by 810, we get 9 and a remainder of 310.
The next digit of our result is 9. 
Result so far: 39030.92716049
Subtract 7290 from 7600 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 39030.92716049, with a leftover of 3.1e-07.
