We look at the division of 43487 by 84 
We want to figure out the number of times 43487 can be divided by 84.

On to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 84

On to step 2:
84 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 84

Advancing to step 3:
The number 84 fits into 434 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 420 from 434 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 84

Let's proceed to step 4:
When dividing 148 by 84, we get 1 with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 84 from 148, we get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 84

On to step 5:
84 goes into 647 7 times with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
Deduct 588 from 647 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 6:
84 goes into 590 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.7
Subtracting 588 from 590 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 84, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 517.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 84, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 517.702
Deduct 168 from 200 and we're left 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.

Advancing to step 9:
When dividing 320 by 84, we get 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 517.7023
The remainder is 68 after subtracting 252 from 320.
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 10:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 517.70238
Deduct 672 from 680 and we're left 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 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 517.70238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 84, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 517.7023809
Deduct 756 from 800 and we're left 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.

On to step 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 517.70238095
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.

In conclusion, the division gives 517.70238095 with a balance of 2e-08.
