86447390 divided by 84 
Let's see how many times 84 fits into 86447390.

Let's proceed to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 84

Advancing to step 2:
The number 84 fits into 86 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 84 from 86 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 84

On to step 3:
When dividing 24 by 84, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 24 after subtracting 0 from 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 84

Step 4:
If we divide 244 by 84, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 168 from 244 leaves us with 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 84

On to step 5:
84 can be fit into 767 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 1029.0
If we subtract 756 from 767, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 84

Moving on to step 6:
When dividing 113 by 84, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 10291.0
Subtracting 84 from 113 leaves us with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 84

Let's proceed to step 7:
The number 84 fits into 299 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 102913.0
Subtracting 252 from 299 leaves us with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 84

Advancing to step 8:
84 can be fit into 470 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1029135.0
Subtracting 420 from 470 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 84 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 1029135.5
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 84, we get 9 with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 1029135.59
Subtracting 756 from 800 leaves us 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.

Advancing to step 11:
When dividing 440 by 84, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1029135.595
Subtract 420 from 440 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 12:
84 can be fit into 200 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1029135.5952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
84 goes into 320 3 times with a remainder of 68.
The next digit of our result is 3. 
Result so far: 1029135.59523
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1029135.595238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 15:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1029135.595238
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
If we divide 800 by 84, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 1029135.59523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1029135.59523809 and a remainder of 4.4e-08.
