Let's divide 64552640 by 869
We want to divide 64552640 by 869.

Moving on to step 1:
When dividing 6 by 869, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 869

On to step 2:
869 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 869

Advancing to step 3:
If we divide 645 by 869, we get 0 and a remainder of 645.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 645, we get 645.
Grab the next digit (5) from the dividend, add it to 645, then carry on: 6455 / 869

Step 4:
869 goes into 6455 7 times with a remainder of 372.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 372 after subtracting 6083 from 6455.
Fetch the next digit (2) from the dividend, attach it to 372 and continue: 3722 / 869

Let's proceed to step 5:
869 goes into 3722 4 times with a remainder of 246.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 3476 from 3722 to get 246.
Bring next digit (6) of the dividend behind the 246 and repeat the process: 2466 / 869

Moving on to step 6:
When dividing 2466 by 869, we get 2 with a remainder of 728.
Put 2 as the next digit of the answer. 
Result so far: 742.0
If we take 1738 away from 2466, we end up with 728.
Fetch the next digit (4) from the dividend, attach it to 728 and continue: 7284 / 869

Going ahead to step 7:
7284 divided by 869 is 8 with a remainder of 332.
The next digit of our result is 8. 
Result so far: 7428.0
Subtracting 6952 from 7284 leaves us with 332.
Grab the next digit (0) from the dividend, add it to 332, then carry on: 3320 / 869

Let's proceed to step 8:
3320 divided by 869 is 3 with a remainder of 713.
Record the quotient 3 as the next digit in the result. 
Result so far: 74283.0
The remainder is 713 after subtracting 2607 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Advancing to step 9:
When dividing 7130 by 869, we get 8 with a remainder of 178.
Write down 8 as next digit of the result. 
Result so far: 74283.8
If we subtract 6952 from 7130, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 10:
If we divide 1780 by 869, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 74283.82
Subtracting 1738 from 1780 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
869 can be fit into 420 0 times, resulting in a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 74283.82
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
When dividing 4200 by 869, we get 4 with a remainder of 724.
Put 4 as the next digit of the answer. 
Result so far: 74283.8204
If we subtract 3476 from 4200, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 13:
869 can be fit into 7240 8 times, resulting in a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 74283.82048
The remainder is 288 after subtracting 6952 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
2880 divided by 869 is 3 with a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 74283.820483
The remainder is 273 after subtracting 2607 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 15:
869 can be fit into 2730 3 times, resulting in a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 74283.8204833
Subtract 2607 from 2730 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final outcome is 74283.8204833, with a leftover of 1.23e-06.
