Let's divide 81870869 by 506
We're looking to find how many times 506 goes into 81870869.

On to step 1:
506 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 506

On to step 2:
If we divide 81 by 506, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 506

On to step 3:
506 goes into 818 1 times with a remainder of 312.
The next digit of our result is 1. 
Result so far: 1.0
If we take 506 away from 818, we end up with 312.
Append the next digit (7) from the dividend to 312 and continue with: 3127 / 506

On to step 4:
When dividing 3127 by 506, we get 6 with a remainder of 91.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 3036 from 3127, we get 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 506

Advancing to step 5:
If we divide 910 by 506, we get 1 and a remainder of 404.
Write down 1 as next digit of the result. 
Result so far: 161.0
Deduct 506 from 910 and we're left with 404.
Bring next digit (8) of the dividend behind the 404 and repeat the process: 4048 / 506

Going ahead to step 6:
When dividing 4048 by 506, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1618.0
The remainder is 0 after subtracting 4048 from 4048.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 506

On to step 7:
506 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 16180.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 506

Advancing to step 8:
The number 506 fits into 69 0 times, leaving a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 161800.0
Subtract 0 from 69 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
When dividing 690 by 506, we get 1 with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 161800.1
Subtracting 506 from 690 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
506 goes into 1840 3 times with a remainder of 322.
The number 3 becomes the next digit in our result. 
Result so far: 161800.13
Subtracting 1518 from 1840 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 11:
If we divide 3220 by 506, we get 6 and a remainder of 184.
The next digit of our result is 6. 
Result so far: 161800.136
The remainder is 184 after subtracting 3036 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
506 can be fit into 1840 3 times, resulting in a remainder of 322.
Record the quotient 3 as the next digit in the result. 
Result so far: 161800.1363
Deduct 1518 from 1840 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 13:
If we divide 3220 by 506, we get 6 and a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 161800.13636
Deduct 3036 from 3220 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 14:
506 goes into 1840 3 times with a remainder of 322.
Put 3 as the next digit of the answer. 
Result so far: 161800.136363
The remainder is 322 after subtracting 1518 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 15:
3220 divided by 506 is 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 161800.1363636
If we take 3036 away from 3220, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 16:
506 goes into 1840 3 times with a remainder of 322.
Record the quotient 3 as the next digit in the result. 
Result so far: 161800.13636363
Subtracting 1518 from 1840 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Our division results in 161800.13636363 with a remaining 3.22e-07.
