42621777 divided by 869 
We want to figure out the number of times 42621777 can be divided by 869.

Let's proceed to step 1:
869 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 869

Moving on to step 2:
The number 869 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 869

On to step 3:
The number 869 fits into 426 0 times, leaving a remainder of 426.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Grab the next digit (2) from the dividend, add it to 426, then carry on: 4262 / 869

Moving on to step 4:
869 goes into 4262 4 times with a remainder of 786.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 3476 from 4262, we get 786.
Fetch the next digit (1) from the dividend, attach it to 786 and continue: 7861 / 869

Step 5:
869 can be fit into 7861 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 40 after subtracting 7821 from 7861.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 869

Step 6:
When dividing 407 by 869, we get 0 with a remainder of 407.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
Subtract 0 from 407 to get 407.
Take the next digit (7) from the dividend and append it to 407, then repeat: 4077 / 869

Going ahead to step 7:
4077 divided by 869 is 4 with a remainder of 601.
Use 4 as the next digit of our solution. 
Result so far: 4904.0
If we take 3476 away from 4077, we end up with 601.
Bring next digit (7) of the dividend behind the 601 and repeat the process: 6017 / 869

Let's proceed to step 8:
869 can be fit into 6017 6 times, resulting in a remainder of 803.
Put 6 as the next digit of the answer. 
Result so far: 49046.0
If we subtract 5214 from 6017, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Going ahead to step 9:
8030 divided by 869 is 9 with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 49046.9
If we take 7821 away from 8030, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 10:
The number 869 fits into 2090 2 times, leaving a remainder of 352.
The next digit of our result is 2. 
Result so far: 49046.92
Subtracting 1738 from 2090 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 11:
The number 869 fits into 3520 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 49046.924
Deduct 3476 from 3520 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
If we divide 440 by 869, we get 0 and a remainder of 440.
The next digit of our result is 0. 
Result so far: 49046.924
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 13:
The number 869 fits into 4400 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 49046.92405
Subtract 4345 from 4400 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
550 divided by 869 is 0 with a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 49046.92405
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 15:
If we divide 5500 by 869, we get 6 and a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 49046.9240506
If we take 5214 away from 5500, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 16:
If we divide 2860 by 869, we get 3 and a remainder of 253.
The next digit of our result is 3. 
Result so far: 49046.92405063
Subtract 2607 from 2860 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

After the division, we end up with 49046.92405063 and a remainder of 2.53e-07.
