80488058 ÷ 523 
Our goal is to divide 80488058 by 523.

On to step 1:
The number 523 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 523

On to step 2:
523 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 523

Moving on to step 3:
523 can be fit into 804 1 times, resulting in a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 281 after subtracting 523 from 804.
Grab the next digit (8) from the dividend, add it to 281, then carry on: 2818 / 523

Advancing to step 4:
If we divide 2818 by 523, we get 5 and a remainder of 203.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2615 away from 2818, we end up with 203.
Grab the next digit (8) from the dividend, add it to 203, then carry on: 2038 / 523

Advancing to step 5:
523 goes into 2038 3 times with a remainder of 469.
Write down 3 as next digit of the result. 
Result so far: 153.0
If we take 1569 away from 2038, we end up with 469.
Grab the next digit (0) from the dividend, add it to 469, then carry on: 4690 / 523

Going ahead to step 6:
523 goes into 4690 8 times with a remainder of 506.
Use 8 as the next digit of our solution. 
Result so far: 1538.0
Subtract 4184 from 4690 to get 506.
Take the next digit (5) from the dividend and append it to 506, then repeat: 5065 / 523

Going ahead to step 7:
The number 523 fits into 5065 9 times, leaving a remainder of 358.
Record the quotient 9 as the next digit in the result. 
Result so far: 15389.0
The remainder is 358 after subtracting 4707 from 5065.
Grab the next digit (8) from the dividend, add it to 358, then carry on: 3588 / 523

Let's proceed to step 8:
The number 523 fits into 3588 6 times, leaving a remainder of 450.
Use 6 as the next digit of our solution. 
Result so far: 153896.0
The remainder is 450 after subtracting 3138 from 3588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 9:
523 goes into 4500 8 times with a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 153896.8
If we subtract 4184 from 4500, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 10:
3160 divided by 523 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 153896.86
Subtracting 3138 from 3160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
523 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 153896.86
Deduct 0 from 220 and we're left 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.

Let's proceed to step 12:
If we divide 2200 by 523, we get 4 and a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 153896.8604
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.

Moving on to step 13:
When dividing 1080 by 523, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 153896.86042
The remainder is 34 after subtracting 1046 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
If we divide 340 by 523, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 153896.86042
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
If we divide 3400 by 523, we get 6 and a remainder of 262.
Write down 6 as next digit of the result. 
Result so far: 153896.8604206
Deduct 3138 from 3400 and we're left 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.

Going ahead to step 16:
The number 523 fits into 2620 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 153896.86042065
If we subtract 2615 from 2620, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 153896.86042065, and the remainder is 5e-09.
