We look at the division of 39784499 by 869 
We want to figure out the number of times 39784499 can be divided by 869.

On to step 1:
3 divided by 869 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 869

Let's proceed to step 2:
If we divide 39 by 869, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 869

Moving on to step 3:
If we divide 397 by 869, we get 0 and a remainder of 397.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 397, we end up with 397.
Append the next digit (8) from the dividend to 397 and continue with: 3978 / 869

Advancing to step 4:
The number 869 fits into 3978 4 times, leaving a remainder of 502.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3476 from 3978 leaves us with 502.
Append the next digit (4) from the dividend to 502 and continue with: 5024 / 869

Let's proceed to step 5:
When dividing 5024 by 869, we get 5 with a remainder of 679.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 4345 from 5024, we get 679.
Include the next digit (4) from the dividend after 679, then repeat: 6794 / 869

Moving on to step 6:
869 can be fit into 6794 7 times, resulting in a remainder of 711.
Use 7 as the next digit of our solution. 
Result so far: 457.0
The remainder is 711 after subtracting 6083 from 6794.
Fetch the next digit (9) from the dividend, attach it to 711 and continue: 7119 / 869

Step 7:
If we divide 7119 by 869, we get 8 and a remainder of 167.
Put 8 as the next digit of the answer. 
Result so far: 4578.0
Subtract 6952 from 7119 to get 167.
Grab the next digit (9) from the dividend, add it to 167, then carry on: 1679 / 869

Let's proceed to step 8:
The number 869 fits into 1679 1 times, leaving a remainder of 810.
The number 1 becomes the next digit in our result. 
Result so far: 45781.0
If we take 869 away from 1679, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Let's proceed to step 9:
The number 869 fits into 8100 9 times, leaving a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 45781.9
If we subtract 7821 from 8100, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 10:
2790 divided by 869 is 3 with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 45781.93
The remainder is 183 after subtracting 2607 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 11:
869 goes into 1830 2 times with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 45781.932
Deduct 1738 from 1830 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 12:
The number 869 fits into 920 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 45781.9321
Subtract 869 from 920 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
510 divided by 869 is 0 with a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 45781.9321
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 14:
5100 divided by 869 is 5 with a remainder of 755.
Write down 5 as next digit of the result. 
Result so far: 45781.932105
Deduct 4345 from 5100 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 15:
When dividing 7550 by 869, we get 8 with a remainder of 598.
The next digit of our result is 8. 
Result so far: 45781.9321058
If we subtract 6952 from 7550, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 16:
The number 869 fits into 5980 6 times, leaving a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 45781.93210586
Subtract 5214 from 5980 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

The final result is 45781.93210586 with a remainder of 7.66e-07.
