We're dividing 38700391 by 564 
We want to figure out the number of times 38700391 can be divided by 564.

On to step 1:
If we divide 3 by 564, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 564

On to step 2:
The number 564 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 564

Advancing to step 3:
If we divide 387 by 564, we get 0 and a remainder of 387.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 387 to get 387.
Bring next digit (0) of the dividend behind the 387 and repeat the process: 3870 / 564

Going ahead to step 4:
3870 divided by 564 is 6 with a remainder of 486.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 3384 away from 3870, we end up with 486.
Bring next digit (0) of the dividend behind the 486 and repeat the process: 4860 / 564

Step 5:
4860 divided by 564 is 8 with a remainder of 348.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 4512 away from 4860, we end up with 348.
Fetch the next digit (3) from the dividend, attach it to 348 and continue: 3483 / 564

On to step 6:
564 can be fit into 3483 6 times, resulting in a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 686.0
If we take 3384 away from 3483, we end up with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 564

On to step 7:
If we divide 999 by 564, we get 1 and a remainder of 435.
The next digit of our result is 1. 
Result so far: 6861.0
The remainder is 435 after subtracting 564 from 999.
Append the next digit (1) from the dividend to 435 and continue with: 4351 / 564

Let's proceed to step 8:
If we divide 4351 by 564, we get 7 and a remainder of 403.
The next digit of our result is 7. 
Result so far: 68617.0
If we subtract 3948 from 4351, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 9:
If we divide 4030 by 564, we get 7 and a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 68617.7
Subtracting 3948 from 4030 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
564 goes into 820 1 times with a remainder of 256.
Record the quotient 1 as the next digit in the result. 
Result so far: 68617.71
If we subtract 564 from 820, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 11:
If we divide 2560 by 564, we get 4 and a remainder of 304.
The next digit of our result is 4. 
Result so far: 68617.714
If we take 2256 away from 2560, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 12:
3040 divided by 564 is 5 with a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 68617.7145
Subtracting 2820 from 3040 leaves us 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.

Advancing to step 13:
The number 564 fits into 2200 3 times, leaving a remainder of 508.
The number 3 becomes the next digit in our result. 
Result so far: 68617.71453
If we subtract 1692 from 2200, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 14:
The number 564 fits into 5080 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 68617.714539
If we subtract 5076 from 5080, we 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 15:
564 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 68617.714539
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
If we divide 400 by 564, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 68617.714539
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 68617.714539 with a remainder of 4e-07.
