We look at the division of 85197579 by 531 
We're looking to find how many times 531 goes into 85197579.

Let's proceed to step 1:
8 divided by 531 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 531

Moving on to step 2:
531 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 531

Step 3:
When dividing 851 by 531, we get 1 with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 531 from 851 and we're left with 320.
Append the next digit (9) from the dividend to 320 and continue with: 3209 / 531

Advancing to step 4:
If we divide 3209 by 531, we get 6 and a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 3186 from 3209, we get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 531

Advancing to step 5:
237 divided by 531 is 0 with a remainder of 237.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtract 0 from 237 to get 237.
Fetch the next digit (5) from the dividend, attach it to 237 and continue: 2375 / 531

Let's proceed to step 6:
If we divide 2375 by 531, we get 4 and a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
Subtracting 2124 from 2375 leaves us with 251.
Grab the next digit (7) from the dividend, add it to 251, then carry on: 2517 / 531

Moving on to step 7:
531 can be fit into 2517 4 times, resulting in a remainder of 393.
Write down 4 as next digit of the result. 
Result so far: 16044.0
If we subtract 2124 from 2517, we get 393.
Include the next digit (9) from the dividend after 393, then repeat: 3939 / 531

Step 8:
531 goes into 3939 7 times with a remainder of 222.
Write down 7 as next digit of the result. 
Result so far: 160447.0
The remainder is 222 after subtracting 3717 from 3939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 9:
2220 divided by 531 is 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 160447.4
Subtract 2124 from 2220 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
If we divide 960 by 531, we get 1 and a remainder of 429.
Use 1 as the next digit of our solution. 
Result so far: 160447.41
Subtract 531 from 960 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 11:
If we divide 4290 by 531, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 160447.418
If we take 4248 away from 4290, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
When dividing 420 by 531, we get 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 160447.418
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 13:
If we divide 4200 by 531, we get 7 and a remainder of 483.
The next digit of our result is 7. 
Result so far: 160447.41807
If we take 3717 away from 4200, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 14:
531 can be fit into 4830 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 160447.418079
Deduct 4779 from 4830 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 15:
510 divided by 531 is 0 with a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 160447.418079
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 16:
When dividing 5100 by 531, we get 9 with a remainder of 321.
The number 9 becomes the next digit in our result. 
Result so far: 160447.41807909
Subtracting 4779 from 5100 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

The final outcome is 160447.41807909, with a leftover of 3.21e-07.
