Let's divide 31080020 by 380
Our goal is to divide 31080020 by 380.

Moving on to step 1:
If we divide 3 by 380, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 380

Going ahead to step 2:
If we divide 31 by 380, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 380

On to step 3:
310 divided by 380 is 0 with a remainder of 310.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 310 after subtracting 0 from 310.
Append the next digit (8) from the dividend to 310 and continue with: 3108 / 380

Going ahead to step 4:
380 can be fit into 3108 8 times, resulting in a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 3040 away from 3108, we end up with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 380

Step 5:
If we divide 680 by 380, we get 1 and a remainder of 300.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 380 from 680, we get 300.
Bring next digit (0) of the dividend behind the 300 and repeat the process: 3000 / 380

Let's proceed to step 6:
The number 380 fits into 3000 7 times, leaving a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 817.0
The remainder is 340 after subtracting 2660 from 3000.
Take the next digit (2) from the dividend and append it to 340, then repeat: 3402 / 380

Step 7:
3402 divided by 380 is 8 with a remainder of 362.
The next digit of our result is 8. 
Result so far: 8178.0
If we subtract 3040 from 3402, we get 362.
Bring next digit (0) of the dividend behind the 362 and repeat the process: 3620 / 380

Advancing to step 8:
The number 380 fits into 3620 9 times, leaving a remainder of 200.
The next digit of our result is 9. 
Result so far: 81789.0
Deduct 3420 from 3620 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
When dividing 2000 by 380, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 81789.5
If we take 1900 away from 2000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
When dividing 1000 by 380, we get 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 81789.52
Subtracting 760 from 1000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
The number 380 fits into 2400 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 81789.526
Deduct 2280 from 2400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
The number 380 fits into 1200 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 81789.5263
The remainder is 60 after subtracting 1140 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
600 divided by 380 is 1 with a remainder of 220.
The next digit of our result is 1. 
Result so far: 81789.52631
Deduct 380 from 600 and we're left 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.

Going ahead to step 14:
If we divide 2200 by 380, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 81789.526315
Subtracting 1900 from 2200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
The number 380 fits into 3000 7 times, leaving a remainder of 340.
The next digit of our result is 7. 
Result so far: 81789.5263157
If we take 2660 away from 3000, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 16:
The number 380 fits into 3400 8 times, leaving a remainder of 360.
The next digit of our result is 8. 
Result so far: 81789.52631578
If we subtract 3040 from 3400, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 81789.52631578 with a remainder of 3.6e-07.
