We're dividing 64574299 by 816 
We want to divide 64574299 by 816.

Let's proceed to step 1:
816 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 816

Advancing to step 2:
64 divided by 816 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 816

On to step 3:
816 can be fit into 645 0 times, resulting in a remainder of 645.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 645 leaves us with 645.
Fetch the next digit (7) from the dividend, attach it to 645 and continue: 6457 / 816

Let's proceed to step 4:
If we divide 6457 by 816, we get 7 and a remainder of 745.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5712 away from 6457, we end up with 745.
Fetch the next digit (4) from the dividend, attach it to 745 and continue: 7454 / 816

Moving on to step 5:
If we divide 7454 by 816, we get 9 and a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 7344 from 7454 leaves us with 110.
Include the next digit (2) from the dividend after 110, then repeat: 1102 / 816

Let's proceed to step 6:
1102 divided by 816 is 1 with a remainder of 286.
Put 1 as the next digit of the answer. 
Result so far: 791.0
If we subtract 816 from 1102, we get 286.
Append the next digit (9) from the dividend to 286 and continue with: 2869 / 816

Let's proceed to step 7:
2869 divided by 816 is 3 with a remainder of 421.
Write down 3 as next digit of the result. 
Result so far: 7913.0
If we take 2448 away from 2869, we end up with 421.
Bring next digit (9) of the dividend behind the 421 and repeat the process: 4219 / 816

On to step 8:
816 can be fit into 4219 5 times, resulting in a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 79135.0
Subtracting 4080 from 4219 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
The number 816 fits into 1390 1 times, leaving a remainder of 574.
Use 1 as the next digit of our solution. 
Result so far: 79135.1
Subtracting 816 from 1390 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 10:
When dividing 5740 by 816, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 79135.17
If we take 5712 away from 5740, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 816 is 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 79135.17
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
816 goes into 2800 3 times with a remainder of 352.
Write down 3 as next digit of the result. 
Result so far: 79135.1703
Subtracting 2448 from 2800 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 13:
The number 816 fits into 3520 4 times, leaving a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 79135.17034
If we take 3264 away from 3520, we end up with 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 14:
When dividing 2560 by 816, we get 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 79135.170343
Subtract 2448 from 2560 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
1120 divided by 816 is 1 with a remainder of 304.
The next digit of our result is 1. 
Result so far: 79135.1703431
Deduct 816 from 1120 and we're left 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.

Advancing to step 16:
If we divide 3040 by 816, we get 3 and a remainder of 592.
Write down 3 as next digit of the result. 
Result so far: 79135.17034313
Subtracting 2448 from 3040 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final result is 79135.17034313 with a remainder of 5.92e-07.
