We look at the division of 64897679 by 810 
Our goal is to divide 64897679 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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 810

Advancing to step 2:
64 divided by 810 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 810

On to step 3:
810 can be fit into 648 0 times, resulting in a remainder of 648.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 648 and we're left with 648.
Fetch the next digit (9) from the dividend, attach it to 648 and continue: 6489 / 810

Let's proceed to step 4:
810 can be fit into 6489 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6480 from 6489 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 810

Going ahead to step 5:
97 divided by 810 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (6) from the dividend, add it to 97, then carry on: 976 / 810

Going ahead to step 6:
976 divided by 810 is 1 with a remainder of 166.
Write down 1 as next digit of the result. 
Result so far: 801.0
Subtracting 810 from 976 leaves us with 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 810

Let's proceed to step 7:
When dividing 1667 by 810, we get 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 8012.0
Subtracting 1620 from 1667 leaves us with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 810

On to step 8:
810 can be fit into 479 0 times, resulting in a remainder of 479.
Put 0 as the next digit of the answer. 
Result so far: 80120.0
Subtracting 0 from 479 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 9:
The number 810 fits into 4790 5 times, leaving a remainder of 740.
The number 5 becomes the next digit in our result. 
Result so far: 80120.5
The remainder is 740 after subtracting 4050 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 10:
810 goes into 7400 9 times with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 80120.59
Deduct 7290 from 7400 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
810 can be fit into 1100 1 times, resulting in a remainder of 290.
Record the quotient 1 as the next digit in the result. 
Result so far: 80120.591
The remainder is 290 after subtracting 810 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
If we divide 2900 by 810, we get 3 and a remainder of 470.
Put 3 as the next digit of the answer. 
Result so far: 80120.5913
The remainder is 470 after subtracting 2430 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 13:
810 goes into 4700 5 times with a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 80120.59135
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.

Moving on to step 14:
810 goes into 6500 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 80120.591358
Subtract 6480 from 6500 to 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.

On to step 15:
When dividing 200 by 810, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 80120.591358
If we take 0 away from 200, we end up 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 16:
The number 810 fits into 2000 2 times, leaving a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 80120.59135802
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.

The quotient of the division is 80120.59135802, and the remainder is 3.8e-07.
