870376 divided by 84 
We want to figure out the number of times 870376 can be divided by 84.

Let's proceed to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 84

Going ahead to step 2:
84 can be fit into 87 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 84 from 87 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 84

On to step 3:
When dividing 30 by 84, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 84

Advancing to step 4:
84 goes into 303 3 times with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 252 from 303 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 84

Advancing to step 5:
84 goes into 517 6 times with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 1036.0
If we take 504 away from 517, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 84

Step 6:
The number 84 fits into 136 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 10361.0
If we subtract 84 from 136, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
84 goes into 520 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10361.6
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 10361.61
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
760 divided by 84 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 10361.619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10361.619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 84, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 10361.61904
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
84 can be fit into 640 7 times, resulting in a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 10361.619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
If we divide 520 by 84, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 10361.6190476
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 84, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 10361.61904761
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 10361.61904761, with a leftover of 7.6e-08.
