Let's divide 80131901 by 578
Our goal is to divide 80131901 by 578.

Step 1:
If we divide 8 by 578, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 578

On to step 2:
When dividing 80 by 578, we get 0 with 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.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 578

Going ahead to step 3:
801 divided by 578 is 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 223 after subtracting 578 from 801.
Take the next digit (3) from the dividend and append it to 223, then repeat: 2233 / 578

Going ahead to step 4:
The number 578 fits into 2233 3 times, leaving a remainder of 499.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1734 away from 2233, we end up with 499.
Take the next digit (1) from the dividend and append it to 499, then repeat: 4991 / 578

Let's proceed to step 5:
If we divide 4991 by 578, we get 8 and a remainder of 367.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Subtracting 4624 from 4991 leaves us with 367.
Fetch the next digit (9) from the dividend, attach it to 367 and continue: 3679 / 578

Let's proceed to step 6:
The number 578 fits into 3679 6 times, leaving a remainder of 211.
Write down 6 as next digit of the result. 
Result so far: 1386.0
Subtract 3468 from 3679 to get 211.
Grab the next digit (0) from the dividend, add it to 211, then carry on: 2110 / 578

Going ahead to step 7:
578 goes into 2110 3 times with a remainder of 376.
Use 3 as the next digit of our solution. 
Result so far: 13863.0
The remainder is 376 after subtracting 1734 from 2110.
Include the next digit (1) from the dividend after 376, then repeat: 3761 / 578

Let's proceed to step 8:
The number 578 fits into 3761 6 times, leaving a remainder of 293.
The number 6 becomes the next digit in our result. 
Result so far: 138636.0
Subtract 3468 from 3761 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 9:
If we divide 2930 by 578, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 138636.5
If we subtract 2890 from 2930, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 578, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 138636.5
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
If we divide 4000 by 578, we get 6 and a remainder of 532.
The next digit of our result is 6. 
Result so far: 138636.506
Subtract 3468 from 4000 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 12:
The number 578 fits into 5320 9 times, leaving a remainder of 118.
Write down 9 as next digit of the result. 
Result so far: 138636.5069
If we take 5202 away from 5320, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 13:
1180 divided by 578 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 138636.50692
If we subtract 1156 from 1180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 578, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 138636.50692
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 15:
If we divide 2400 by 578, we get 4 and a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 138636.5069204
If we take 2312 away from 2400, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 16:
When dividing 880 by 578, we get 1 with a remainder of 302.
The next digit of our result is 1. 
Result so far: 138636.50692041
If we take 578 away from 880, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The final outcome is 138636.50692041, with a leftover of 3.02e-07.
