We divide 87160379 by 521
Our goal is to divide 87160379 by 521.

Advancing to step 1:
521 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 521

Going ahead to step 2:
521 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 521

Moving on to step 3:
871 divided by 521 is 1 with a remainder of 350.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 521 from 871 to get 350.
Bring next digit (6) of the dividend behind the 350 and repeat the process: 3506 / 521

Step 4:
When dividing 3506 by 521, we get 6 with a remainder of 380.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 3126 from 3506 and we're left with 380.
Include the next digit (0) from the dividend after 380, then repeat: 3800 / 521

Advancing to step 5:
521 can be fit into 3800 7 times, resulting in a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtracting 3647 from 3800 leaves us with 153.
Grab the next digit (3) from the dividend, add it to 153, then carry on: 1533 / 521

Moving on to step 6:
When dividing 1533 by 521, we get 2 with a remainder of 491.
Write down 2 as next digit of the result. 
Result so far: 1672.0
Deduct 1042 from 1533 and we're left with 491.
Bring next digit (7) of the dividend behind the 491 and repeat the process: 4917 / 521

Going ahead to step 7:
521 goes into 4917 9 times with a remainder of 228.
Write down 9 as next digit of the result. 
Result so far: 16729.0
The remainder is 228 after subtracting 4689 from 4917.
Include the next digit (9) from the dividend after 228, then repeat: 2289 / 521

Going ahead to step 8:
521 can be fit into 2289 4 times, resulting in a remainder of 205.
Use 4 as the next digit of our solution. 
Result so far: 167294.0
Subtract 2084 from 2289 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 9:
521 can be fit into 2050 3 times, resulting in a remainder of 487.
Record the quotient 3 as the next digit in the result. 
Result so far: 167294.3
If we subtract 1563 from 2050, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Going ahead to step 10:
When dividing 4870 by 521, we get 9 with a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 167294.39
If we take 4689 away from 4870, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 11:
The number 521 fits into 1810 3 times, leaving a remainder of 247.
The next digit of our result is 3. 
Result so far: 167294.393
Subtracting 1563 from 1810 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 12:
When dividing 2470 by 521, we get 4 with a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 167294.3934
If we take 2084 away from 2470, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 13:
521 goes into 3860 7 times with a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 167294.39347
Deduct 3647 from 3860 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 14:
The number 521 fits into 2130 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 167294.393474
Subtract 2084 from 2130 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
521 can be fit into 460 0 times, resulting in a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 167294.393474
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 16:
When dividing 4600 by 521, we get 8 with a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 167294.39347408
If we take 4168 away from 4600, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final outcome is 167294.39347408, with a leftover of 4.32e-07.
