We divide 81439299 by 388
We want to figure out the number of times 81439299 can be divided by 388.

Step 1:
When dividing 8 by 388, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 388

Going ahead to step 2:
81 divided by 388 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 388

Advancing to step 3:
814 divided by 388 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 776 away from 814, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 388

Going ahead to step 4:
383 divided by 388 is 0 with a remainder of 383.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 383, we end up with 383.
Append the next digit (9) from the dividend to 383 and continue with: 3839 / 388

Step 5:
388 can be fit into 3839 9 times, resulting in a remainder of 347.
The next digit of our result is 9. 
Result so far: 209.0
Subtract 3492 from 3839 to get 347.
Take the next digit (2) from the dividend and append it to 347, then repeat: 3472 / 388

On to step 6:
If we divide 3472 by 388, we get 8 and a remainder of 368.
The next digit of our result is 8. 
Result so far: 2098.0
Subtract 3104 from 3472 to get 368.
Bring next digit (9) of the dividend behind the 368 and repeat the process: 3689 / 388

Going ahead to step 7:
When dividing 3689 by 388, we get 9 with a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 20989.0
The remainder is 197 after subtracting 3492 from 3689.
Include the next digit (9) from the dividend after 197, then repeat: 1979 / 388

On to step 8:
388 can be fit into 1979 5 times, resulting in a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 209895.0
Deduct 1940 from 1979 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
If we divide 390 by 388, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 209895.1
Deduct 388 from 390 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 388, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 209895.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 388, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 209895.1
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 209895.1, with a leftover of 0.02.
