851870 divided by 84 
Let's see how many times 84 fits into 851870.

Advancing to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 84

Advancing to step 2:
When dividing 85 by 84, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 84 from 85, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 84

Going ahead to step 3:
11 divided by 84 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 84

Let's proceed to step 4:
The number 84 fits into 118 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 84 away from 118, we end up with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 84

Going ahead to step 5:
The number 84 fits into 347 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 1014.0
The remainder is 11 after subtracting 336 from 347.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 84

Let's proceed to step 6:
84 goes into 110 1 times with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 10141.0
Subtract 84 from 110 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
260 divided by 84 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 10141.3
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 84 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 10141.3
Deduct 0 from 80 and we're left 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.

Step 9:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 10141.309
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
440 divided by 84 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 10141.3095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
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: 10141.30952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
84 goes into 320 3 times with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 10141.309523
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10141.3095238
If we take 672 away from 680, we end up 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.

Advancing to step 14:
84 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 10141.3095238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 10141.3095238 with a remainder of 8e-08.
