83702530 divided by 31 
We want to divide 83702530 by 31.

On to step 1:
When dividing 8 by 31, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 31

On to step 2:
When dividing 83 by 31, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 62 from 83 and we're left with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 31

Step 3:
When dividing 217 by 31, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 217 from 217 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 31

Going ahead to step 4:
The number 31 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 270.0
If we subtract 0 from 0, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 31

Advancing to step 5:
When dividing 2 by 31, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 2700.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 31

On to step 6:
The number 31 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 27000.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 31

Moving on to step 7:
31 can be fit into 253 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 270008.0
Subtract 248 from 253 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 31

Let's proceed to step 8:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2700081.0
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 9:
If we divide 190 by 31, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 2700081.6
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 31 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2700081.61
The remainder is 9 after subtracting 31 from 40.
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 11:
If we divide 90 by 31, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2700081.612
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
When dividing 280 by 31, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2700081.6129
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.

Let's proceed to step 13:
If we divide 10 by 31, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2700081.6129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 2700081.612903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 15:
31 goes into 70 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2700081.6129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
If we divide 80 by 31, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2700081.61290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 2700081.61290322 with a balance of 1.8e-08.
