We divide 8511037 by 388
We want to figure out the number of times 8511037 can be divided by 388.

Step 1:
When dividing 8 by 388, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 388

Going ahead to step 2:
388 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 388

Step 3:
The number 388 fits into 851 2 times, leaving a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 776 away from 851, we end up with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 388

Advancing to step 4:
388 goes into 751 1 times with a remainder of 363.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 388 from 751, we get 363.
Include the next digit (0) from the dividend after 363, then repeat: 3630 / 388

Step 5:
The number 388 fits into 3630 9 times, leaving a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 219.0
Subtract 3492 from 3630 to get 138.
Append the next digit (3) from the dividend to 138 and continue with: 1383 / 388

Step 6:
388 goes into 1383 3 times with a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 2193.0
The remainder is 219 after subtracting 1164 from 1383.
Grab the next digit (7) from the dividend, add it to 219, then carry on: 2197 / 388

Advancing to step 7:
When dividing 2197 by 388, we get 5 with a remainder of 257.
Record the quotient 5 as the next digit in the result. 
Result so far: 21935.0
Deduct 1940 from 2197 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 8:
388 goes into 2570 6 times with a remainder of 242.
Put 6 as the next digit of the answer. 
Result so far: 21935.6
The remainder is 242 after subtracting 2328 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 9:
2420 divided by 388 is 6 with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 21935.66
If we take 2328 away from 2420, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 21935.66 with a remainder of 0.092.
