83990146 ÷ 530 
Let's see how many times 530 fits into 83990146.

On to step 1:
8 divided by 530 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 530

Step 2:
If we divide 83 by 530, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 530

Let's proceed to step 3:
When dividing 839 by 530, we get 1 with a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 309 after subtracting 530 from 839.
Grab the next digit (9) from the dividend, add it to 309, then carry on: 3099 / 530

On to step 4:
If we divide 3099 by 530, we get 5 and a remainder of 449.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2650 from 3099 leaves us with 449.
Bring next digit (0) of the dividend behind the 449 and repeat the process: 4490 / 530

Moving on to step 5:
4490 divided by 530 is 8 with a remainder of 250.
The next digit of our result is 8. 
Result so far: 158.0
If we subtract 4240 from 4490, we get 250.
Grab the next digit (1) from the dividend, add it to 250, then carry on: 2501 / 530

Moving on to step 6:
When dividing 2501 by 530, we get 4 with a remainder of 381.
Record the quotient 4 as the next digit in the result. 
Result so far: 1584.0
Deduct 2120 from 2501 and we're left with 381.
Append the next digit (4) from the dividend to 381 and continue with: 3814 / 530

Advancing to step 7:
3814 divided by 530 is 7 with a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 15847.0
Subtract 3710 from 3814 to get 104.
Fetch the next digit (6) from the dividend, attach it to 104 and continue: 1046 / 530

Going ahead to step 8:
When dividing 1046 by 530, we get 1 with a remainder of 516.
Put 1 as the next digit of the answer. 
Result so far: 158471.0
Subtract 530 from 1046 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 9:
When dividing 5160 by 530, we get 9 with a remainder of 390.
Use 9 as the next digit of our solution. 
Result so far: 158471.9
Subtracting 4770 from 5160 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
530 goes into 3900 7 times with a remainder of 190.
The number 7 becomes the next digit in our result. 
Result so far: 158471.97
If we subtract 3710 from 3900, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
530 goes into 1900 3 times with a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 158471.973
Subtracting 1590 from 1900 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 12:
If we divide 3100 by 530, we get 5 and a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 158471.9735
If we subtract 2650 from 3100, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 13:
530 goes into 4500 8 times with a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 158471.97358
The remainder is 260 after subtracting 4240 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 14:
The number 530 fits into 2600 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 158471.973584
Subtract 2120 from 2600 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 15:
When dividing 4800 by 530, we get 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 158471.9735849
The remainder is 30 after subtracting 4770 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
530 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 158471.9735849
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 158471.9735849 with a remaining 3e-07.
