We divide 81846815 by 521
We're looking to find how many times 521 goes into 81846815.

On to step 1:
The number 521 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 521

Moving on to step 2:
521 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 521

Advancing to step 3:
When dividing 818 by 521, we get 1 with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 521 from 818 leaves us with 297.
Grab the next digit (4) from the dividend, add it to 297, then carry on: 2974 / 521

Step 4:
When dividing 2974 by 521, we get 5 with a remainder of 369.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2605 from 2974 to get 369.
Take the next digit (6) from the dividend and append it to 369, then repeat: 3696 / 521

Step 5:
The number 521 fits into 3696 7 times, leaving a remainder of 49.
The next digit of our result is 7. 
Result so far: 157.0
Deduct 3647 from 3696 and we're left with 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 521

Going ahead to step 6:
498 divided by 521 is 0 with a remainder of 498.
The number 0 becomes the next digit in our result. 
Result so far: 1570.0
If we subtract 0 from 498, we get 498.
Append the next digit (1) from the dividend to 498 and continue with: 4981 / 521

Advancing to step 7:
4981 divided by 521 is 9 with a remainder of 292.
Write down 9 as next digit of the result. 
Result so far: 15709.0
Subtract 4689 from 4981 to get 292.
Take the next digit (5) from the dividend and append it to 292, then repeat: 2925 / 521

Moving on to step 8:
2925 divided by 521 is 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 157095.0
If we subtract 2605 from 2925, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
521 goes into 3200 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 157095.6
If we subtract 3126 from 3200, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
The number 521 fits into 740 1 times, leaving a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 157095.61
If we subtract 521 from 740, 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.

Advancing to step 11:
521 can be fit into 2190 4 times, resulting in a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 157095.614
The remainder is 106 after subtracting 2084 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 12:
1060 divided by 521 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 157095.6142
If we subtract 1042 from 1060, we get 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 13:
180 divided by 521 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 157095.6142
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
If we divide 1800 by 521, we get 3 and a remainder of 237.
The number 3 becomes the next digit in our result. 
Result so far: 157095.614203
The remainder is 237 after subtracting 1563 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 15:
2370 divided by 521 is 4 with a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 157095.6142034
Deduct 2084 from 2370 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 16:
If we divide 2860 by 521, we get 5 and a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 157095.61420345
Subtract 2605 from 2860 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

After the division, we end up with 157095.61420345 and a remainder of 2.55e-07.
