We divide 55578839 by 869
We want to divide 55578839 by 869.

Step 1:
When dividing 5 by 869, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 869

Step 2:
55 divided by 869 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 869

Going ahead to step 3:
555 divided by 869 is 0 with a remainder of 555.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 555 and we're left with 555.
Fetch the next digit (7) from the dividend, attach it to 555 and continue: 5557 / 869

On to step 4:
When dividing 5557 by 869, we get 6 with a remainder of 343.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 5214 from 5557, we get 343.
Grab the next digit (8) from the dividend, add it to 343, then carry on: 3438 / 869

Step 5:
The number 869 fits into 3438 3 times, leaving a remainder of 831.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtracting 2607 from 3438 leaves us with 831.
Include the next digit (8) from the dividend after 831, then repeat: 8318 / 869

Let's proceed to step 6:
8318 divided by 869 is 9 with a remainder of 497.
Write down 9 as next digit of the result. 
Result so far: 639.0
Deduct 7821 from 8318 and we're left with 497.
Bring next digit (3) of the dividend behind the 497 and repeat the process: 4973 / 869

Step 7:
When dividing 4973 by 869, we get 5 with a remainder of 628.
The number 5 becomes the next digit in our result. 
Result so far: 6395.0
Subtract 4345 from 4973 to get 628.
Grab the next digit (9) from the dividend, add it to 628, then carry on: 6289 / 869

Advancing to step 8:
The number 869 fits into 6289 7 times, leaving a remainder of 206.
The number 7 becomes the next digit in our result. 
Result so far: 63957.0
Subtract 6083 from 6289 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 9:
If we divide 2060 by 869, we get 2 and a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 63957.2
The remainder is 322 after subtracting 1738 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 10:
If we divide 3220 by 869, we get 3 and a remainder of 613.
Use 3 as the next digit of our solution. 
Result so far: 63957.23
Subtracting 2607 from 3220 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Step 11:
869 can be fit into 6130 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 63957.237
Subtract 6083 from 6130 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
The number 869 fits into 470 0 times, leaving a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 63957.237
Deduct 0 from 470 and we're left with 470.
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:
If we divide 4700 by 869, we get 5 and a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 63957.23705
The remainder is 355 after subtracting 4345 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 14:
3550 divided by 869 is 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 63957.237054
If we subtract 3476 from 3550, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 15:
The number 869 fits into 740 0 times, leaving a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 63957.237054
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 16:
869 goes into 7400 8 times with a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 63957.23705408
If we subtract 6952 from 7400, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final result is 63957.23705408 with a remainder of 4.48e-07.
