689658 ÷ 84 
We want to divide 689658 by 84.

On to step 1:
6 divided by 84 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 84

Advancing to step 2:
If we divide 68 by 84, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 84

Going ahead to step 3:
84 goes into 689 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 672 from 689 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 84

Step 4:
84 goes into 176 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 168 from 176 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 84

Let's proceed to step 5:
The number 84 fits into 85 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 821.0
Deduct 84 from 85 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 84

Going ahead to step 6:
If we divide 18 by 84, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 8210.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 84 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 8210.2
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 8210.21
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
If we divide 360 by 84, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8210.214
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8210.2142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
If we divide 720 by 84, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8210.21428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8210.214285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
84 goes into 600 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8210.2142857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 8210.21428571
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 8210.21428571 with a balance of 3.6e-08.
