We divide 83120900 by 385
We want to figure out the number of times 83120900 can be divided by 385.

On to step 1:
385 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 385

Let's proceed to step 2:
385 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 385

Going ahead to step 3:
If we divide 831 by 385, we get 2 and a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 770 from 831 leaves us with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 385

Going ahead to step 4:
385 can be fit into 612 1 times, resulting in a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 385 from 612, we get 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 385

Going ahead to step 5:
The number 385 fits into 2270 5 times, leaving a remainder of 345.
The next digit of our result is 5. 
Result so far: 215.0
Deduct 1925 from 2270 and we're left with 345.
Bring next digit (9) of the dividend behind the 345 and repeat the process: 3459 / 385

Step 6:
The number 385 fits into 3459 8 times, leaving a remainder of 379.
The next digit of our result is 8. 
Result so far: 2158.0
Deduct 3080 from 3459 and we're left with 379.
Bring next digit (0) of the dividend behind the 379 and repeat the process: 3790 / 385

Moving on to step 7:
385 can be fit into 3790 9 times, resulting in a remainder of 325.
Write down 9 as next digit of the result. 
Result so far: 21589.0
The remainder is 325 after subtracting 3465 from 3790.
Append the next digit (0) from the dividend to 325 and continue with: 3250 / 385

Going ahead to step 8:
The number 385 fits into 3250 8 times, leaving a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 215898.0
Deduct 3080 from 3250 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
The number 385 fits into 1700 4 times, leaving a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 215898.4
Deduct 1540 from 1700 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
385 goes into 1600 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 215898.44
Deduct 1540 from 1600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 215898.44, with a leftover of 0.06.
