We divide 91518726 by 531
We want to figure out the number of times 91518726 can be divided by 531.

Step 1:
When dividing 9 by 531, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 531

On to step 2:
531 can be fit into 91 0 times, resulting in a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 531

Going ahead to step 3:
The number 531 fits into 915 1 times, leaving a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 531 from 915 and we're left with 384.
Bring next digit (1) of the dividend behind the 384 and repeat the process: 3841 / 531

On to step 4:
531 goes into 3841 7 times with a remainder of 124.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 3717 from 3841 leaves us with 124.
Append the next digit (8) from the dividend to 124 and continue with: 1248 / 531

Moving on to step 5:
The number 531 fits into 1248 2 times, leaving a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 172.0
The remainder is 186 after subtracting 1062 from 1248.
Fetch the next digit (7) from the dividend, attach it to 186 and continue: 1867 / 531

Step 6:
531 can be fit into 1867 3 times, resulting in a remainder of 274.
The next digit of our result is 3. 
Result so far: 1723.0
Subtract 1593 from 1867 to get 274.
Bring next digit (2) of the dividend behind the 274 and repeat the process: 2742 / 531

On to step 7:
If we divide 2742 by 531, we get 5 and a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 17235.0
Subtracting 2655 from 2742 leaves us with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 531

Let's proceed to step 8:
The number 531 fits into 876 1 times, leaving a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 172351.0
If we take 531 away from 876, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 9:
When dividing 3450 by 531, we get 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 172351.6
The remainder is 264 after subtracting 3186 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
The number 531 fits into 2640 4 times, leaving a remainder of 516.
Write down 4 as next digit of the result. 
Result so far: 172351.64
The remainder is 516 after subtracting 2124 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 11:
531 goes into 5160 9 times with a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 172351.649
Deduct 4779 from 5160 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 12:
The number 531 fits into 3810 7 times, leaving a remainder of 93.
The next digit of our result is 7. 
Result so far: 172351.6497
If we subtract 3717 from 3810, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 13:
If we divide 930 by 531, we get 1 and a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 172351.64971
Deduct 531 from 930 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 14:
If we divide 3990 by 531, we get 7 and a remainder of 273.
The next digit of our result is 7. 
Result so far: 172351.649717
Subtract 3717 from 3990 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 15:
531 goes into 2730 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 172351.6497175
The remainder is 75 after subtracting 2655 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
531 can be fit into 750 1 times, resulting in a remainder of 219.
The next digit of our result is 1. 
Result so far: 172351.64971751
If we subtract 531 from 750, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

The final outcome is 172351.64971751, with a leftover of 2.19e-07.
