25031668 ÷ 869 
We want to figure out the number of times 25031668 can be divided by 869.

On to step 1:
If we divide 2 by 869, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 869

On to step 2:
869 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 869

Let's proceed to step 3:
If we divide 250 by 869, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 250, we get 250.
Take the next digit (3) from the dividend and append it to 250, then repeat: 2503 / 869

Advancing to step 4:
869 can be fit into 2503 2 times, resulting in a remainder of 765.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1738 from 2503 and we're left with 765.
Grab the next digit (1) from the dividend, add it to 765, then carry on: 7651 / 869

Moving on to step 5:
869 goes into 7651 8 times with a remainder of 699.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 6952 from 7651, we get 699.
Bring next digit (6) of the dividend behind the 699 and repeat the process: 6996 / 869

Step 6:
If we divide 6996 by 869, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
Subtracting 6952 from 6996 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 869

Advancing to step 7:
If we divide 446 by 869, we get 0 and a remainder of 446.
Write down 0 as next digit of the result. 
Result so far: 2880.0
The remainder is 446 after subtracting 0 from 446.
Include the next digit (8) from the dividend after 446, then repeat: 4468 / 869

On to step 8:
869 can be fit into 4468 5 times, resulting in a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 28805.0
The remainder is 123 after subtracting 4345 from 4468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 9:
869 goes into 1230 1 times with a remainder of 361.
The number 1 becomes the next digit in our result. 
Result so far: 28805.1
The remainder is 361 after subtracting 869 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 10:
When dividing 3610 by 869, we get 4 with a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 28805.14
If we subtract 3476 from 3610, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 11:
869 can be fit into 1340 1 times, resulting in a remainder of 471.
Record the quotient 1 as the next digit in the result. 
Result so far: 28805.141
Deduct 869 from 1340 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 12:
869 can be fit into 4710 5 times, resulting in a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 28805.1415
Subtracting 4345 from 4710 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 13:
869 can be fit into 3650 4 times, resulting in a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 28805.14154
Subtract 3476 from 3650 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 14:
869 can be fit into 1740 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 28805.141542
Subtracting 1738 from 1740 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
When dividing 20 by 869, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 28805.141542
Subtract 0 from 20 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.

Step 16:
When dividing 200 by 869, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 28805.141542
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 28805.141542 with a remaining 2e-07.
