Let's divide 87501258 by 522
We're looking to find how many times 522 goes into 87501258.

On to step 1:
The number 522 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 522

On to step 2:
522 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
If we take 0 away from 87, we end up with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 522

Advancing to step 3:
If we divide 875 by 522, we get 1 and a remainder of 353.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 353 after subtracting 522 from 875.
Include the next digit (0) from the dividend after 353, then repeat: 3530 / 522

Advancing to step 4:
If we divide 3530 by 522, we get 6 and a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 398 after subtracting 3132 from 3530.
Grab the next digit (1) from the dividend, add it to 398, then carry on: 3981 / 522

Step 5:
522 can be fit into 3981 7 times, resulting in a remainder of 327.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Deduct 3654 from 3981 and we're left with 327.
Include the next digit (2) from the dividend after 327, then repeat: 3272 / 522

Advancing to step 6:
The number 522 fits into 3272 6 times, leaving a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 1676.0
If we take 3132 away from 3272, we end up with 140.
Fetch the next digit (5) from the dividend, attach it to 140 and continue: 1405 / 522

Step 7:
522 can be fit into 1405 2 times, resulting in a remainder of 361.
Record the quotient 2 as the next digit in the result. 
Result so far: 16762.0
If we subtract 1044 from 1405, we get 361.
Take the next digit (8) from the dividend and append it to 361, then repeat: 3618 / 522

Step 8:
3618 divided by 522 is 6 with a remainder of 486.
Record the quotient 6 as the next digit in the result. 
Result so far: 167626.0
The remainder is 486 after subtracting 3132 from 3618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 9:
The number 522 fits into 4860 9 times, leaving a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 167626.9
Subtracting 4698 from 4860 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
The number 522 fits into 1620 3 times, leaving a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 167626.93
Deduct 1566 from 1620 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
522 can be fit into 540 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 167626.931
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
522 goes into 180 0 times with a remainder of 180.
The next digit of our result is 0. 
Result so far: 167626.931
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
1800 divided by 522 is 3 with a remainder of 234.
Record the quotient 3 as the next digit in the result. 
Result so far: 167626.93103
Subtracting 1566 from 1800 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 14:
If we divide 2340 by 522, we get 4 and a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 167626.931034
The remainder is 252 after subtracting 2088 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 15:
522 can be fit into 2520 4 times, resulting in a remainder of 432.
The next digit of our result is 4. 
Result so far: 167626.9310344
The remainder is 432 after subtracting 2088 from 2520.
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 167626.9310344, with a leftover of 4.32e-06.
