64354844 ÷ 810 
Our goal is to divide 64354844 by 810.

Going ahead to step 1:
If we divide 6 by 810, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 810

Moving on to step 2:
If we divide 64 by 810, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 810

Advancing to step 3:
643 divided by 810 is 0 with a remainder of 643.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 643, we get 643.
Bring next digit (5) of the dividend behind the 643 and repeat the process: 6435 / 810

Advancing to step 4:
6435 divided by 810 is 7 with a remainder of 765.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5670 from 6435, we get 765.
Take the next digit (4) from the dividend and append it to 765, then repeat: 7654 / 810

Step 5:
When dividing 7654 by 810, we get 9 with a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Deduct 7290 from 7654 and we're left with 364.
Append the next digit (8) from the dividend to 364 and continue with: 3648 / 810

Advancing to step 6:
810 can be fit into 3648 4 times, resulting in a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 794.0
The remainder is 408 after subtracting 3240 from 3648.
Bring next digit (4) of the dividend behind the 408 and repeat the process: 4084 / 810

Let's proceed to step 7:
If we divide 4084 by 810, we get 5 and a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 7945.0
Subtracting 4050 from 4084 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 810

On to step 8:
If we divide 344 by 810, we get 0 and a remainder of 344.
The number 0 becomes the next digit in our result. 
Result so far: 79450.0
Subtracting 0 from 344 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
The number 810 fits into 3440 4 times, leaving a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 79450.4
Deduct 3240 from 3440 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
The number 810 fits into 2000 2 times, leaving a remainder of 380.
The number 2 becomes the next digit in our result. 
Result so far: 79450.42
Deduct 1620 from 2000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
When dividing 3800 by 810, we get 4 with a remainder of 560.
Write down 4 as next digit of the result. 
Result so far: 79450.424
If we subtract 3240 from 3800, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 12:
The number 810 fits into 5600 6 times, leaving a remainder of 740.
Use 6 as the next digit of our solution. 
Result so far: 79450.4246
If we take 4860 away from 5600, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 13:
810 goes into 7400 9 times with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 79450.42469
The remainder is 110 after subtracting 7290 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
810 can be fit into 1100 1 times, resulting in a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 79450.424691
Subtracting 810 from 1100 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 15:
If we divide 2900 by 810, we get 3 and a remainder of 470.
The number 3 becomes the next digit in our result. 
Result so far: 79450.4246913
If we subtract 2430 from 2900, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 16:
When dividing 4700 by 810, we get 5 with a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 79450.42469135
The remainder is 650 after subtracting 4050 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Our division results in 79450.42469135 with a remaining 6.5e-07.
