Let's divide 870988 by 84
We want to divide 870988 by 84.

Advancing to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 84

Step 2:
The number 84 fits into 87 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 84 away from 87, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 84

Step 3:
If we divide 30 by 84, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 84

Advancing to step 4:
84 goes into 309 3 times with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 252 away from 309, we end up with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 84

On to step 5:
84 goes into 578 6 times with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 1036.0
Subtracting 504 from 578 leaves us with 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 84

Step 6:
If we divide 748 by 84, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 10368.0
Subtract 672 from 748 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 7:
If we divide 760 by 84, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 10368.9
Subtract 756 from 760 to 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 8:
84 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10368.9
Subtracting 0 from 40 leaves us 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 9:
400 divided by 84 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 10368.904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
84 goes into 640 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 10368.9047
If we take 588 away from 640, we end up 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.

Let's proceed to step 11:
When dividing 520 by 84, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 10368.90476
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 12:
If we divide 160 by 84, we get 1 and a remainder of 76.
The next digit of our result is 1. 
Result so far: 10368.904761
Deduct 84 from 160 and we're left 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.

Step 13:
84 goes into 760 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 10368.9047619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 84, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10368.9047619
Deduct 0 from 40 and we're left 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.

After the division, we end up with 10368.9047619 and a remainder of 4e-08.
