55559540 ÷ 869 
Our goal is to divide 55559540 by 869.

Going ahead to step 1:
If we divide 5 by 869, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 869

Moving on to step 2:
869 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 869

Moving on to step 3:
The number 869 fits into 555 0 times, leaving a remainder of 555.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 555 leaves us with 555.
Grab the next digit (5) from the dividend, add it to 555, then carry on: 5555 / 869

Step 4:
869 can be fit into 5555 6 times, resulting in a remainder of 341.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5214 from 5555 and we're left with 341.
Bring next digit (9) of the dividend behind the 341 and repeat the process: 3419 / 869

On to step 5:
When dividing 3419 by 869, we get 3 with a remainder of 812.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 2607 from 3419 leaves us with 812.
Include the next digit (5) from the dividend after 812, then repeat: 8125 / 869

Moving on to step 6:
8125 divided by 869 is 9 with a remainder of 304.
The next digit of our result is 9. 
Result so far: 639.0
Subtract 7821 from 8125 to get 304.
Bring next digit (4) of the dividend behind the 304 and repeat the process: 3044 / 869

Let's proceed to step 7:
When dividing 3044 by 869, we get 3 with a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 6393.0
Subtracting 2607 from 3044 leaves us with 437.
Bring next digit (0) of the dividend behind the 437 and repeat the process: 4370 / 869

Going ahead to step 8:
The number 869 fits into 4370 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 63935.0
The remainder is 25 after subtracting 4345 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
250 divided by 869 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 63935.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
869 goes into 2500 2 times with a remainder of 762.
Write down 2 as next digit of the result. 
Result so far: 63935.02
If we subtract 1738 from 2500, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Moving on to step 11:
869 can be fit into 7620 8 times, resulting in a remainder of 668.
The number 8 becomes the next digit in our result. 
Result so far: 63935.028
Subtract 6952 from 7620 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 12:
869 goes into 6680 7 times with a remainder of 597.
Write down 7 as next digit of the result. 
Result so far: 63935.0287
Subtract 6083 from 6680 to get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 13:
869 goes into 5970 6 times with a remainder of 756.
Use 6 as the next digit of our solution. 
Result so far: 63935.02876
Deduct 5214 from 5970 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Moving on to step 14:
The number 869 fits into 7560 8 times, leaving a remainder of 608.
Write down 8 as next digit of the result. 
Result so far: 63935.028768
If we take 6952 away from 7560, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 15:
869 goes into 6080 6 times with a remainder of 866.
Record the quotient 6 as the next digit in the result. 
Result so far: 63935.0287686
Deduct 5214 from 6080 and we're left with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Going ahead to step 16:
8660 divided by 869 is 9 with a remainder of 839.
The number 9 becomes the next digit in our result. 
Result so far: 63935.02876869
If we take 7821 away from 8660, we end up with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Our division results in 63935.02876869 with a remaining 8.39e-07.
