We're dividing 84089531 by 523 
We want to divide 84089531 by 523.

Let's proceed to step 1:
523 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 523

On to step 2:
If we divide 84 by 523, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 523

Moving on to step 3:
If we divide 840 by 523, we get 1 and a remainder of 317.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 523 from 840 and we're left with 317.
Take the next digit (8) from the dividend and append it to 317, then repeat: 3178 / 523

Moving on to step 4:
When dividing 3178 by 523, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 40 after subtracting 3138 from 3178.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 523

On to step 5:
If we divide 409 by 523, we get 0 and a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 409, we get 409.
Fetch the next digit (5) from the dividend, attach it to 409 and continue: 4095 / 523

Step 6:
523 can be fit into 4095 7 times, resulting in a remainder of 434.
The number 7 becomes the next digit in our result. 
Result so far: 1607.0
If we take 3661 away from 4095, we end up with 434.
Bring next digit (3) of the dividend behind the 434 and repeat the process: 4343 / 523

Going ahead to step 7:
523 goes into 4343 8 times with a remainder of 159.
The next digit of our result is 8. 
Result so far: 16078.0
If we subtract 4184 from 4343, we get 159.
Take the next digit (1) from the dividend and append it to 159, then repeat: 1591 / 523

Going ahead to step 8:
When dividing 1591 by 523, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 160783.0
The remainder is 22 after subtracting 1569 from 1591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
The number 523 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 160783.0
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
When dividing 2200 by 523, we get 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 160783.04
If we take 2092 away from 2200, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 11:
523 can be fit into 1080 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 160783.042
Deduct 1046 from 1080 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
523 can be fit into 340 0 times, resulting in a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 160783.042
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 13:
523 goes into 3400 6 times with a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 160783.04206
If we take 3138 away from 3400, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 14:
523 goes into 2620 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 160783.042065
If we take 2615 away from 2620, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
The number 523 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 160783.042065
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
If we divide 500 by 523, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 160783.042065
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 160783.042065 with a remainder of 5e-07.
