Let's divide 83934037 by 509
We're looking to find how many times 509 goes into 83934037.

Advancing to step 1:
8 divided by 509 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 509

On to step 2:
509 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 509

Moving on to step 3:
509 can be fit into 839 1 times, resulting in a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 509 from 839 leaves us with 330.
Take the next digit (3) from the dividend and append it to 330, then repeat: 3303 / 509

Going ahead to step 4:
When dividing 3303 by 509, we get 6 with a remainder of 249.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3054 from 3303 leaves us with 249.
Take the next digit (4) from the dividend and append it to 249, then repeat: 2494 / 509

Step 5:
The number 509 fits into 2494 4 times, leaving a remainder of 458.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 2036 from 2494 and we're left with 458.
Append the next digit (0) from the dividend to 458 and continue with: 4580 / 509

Going ahead to step 6:
509 can be fit into 4580 8 times, resulting in a remainder of 508.
Put 8 as the next digit of the answer. 
Result so far: 1648.0
Deduct 4072 from 4580 and we're left with 508.
Take the next digit (3) from the dividend and append it to 508, then repeat: 5083 / 509

Advancing to step 7:
When dividing 5083 by 509, we get 9 with a remainder of 502.
The number 9 becomes the next digit in our result. 
Result so far: 16489.0
Subtract 4581 from 5083 to get 502.
Append the next digit (7) from the dividend to 502 and continue with: 5027 / 509

Let's proceed to step 8:
When dividing 5027 by 509, we get 9 with a remainder of 446.
Use 9 as the next digit of our solution. 
Result so far: 164899.0
Subtract 4581 from 5027 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
When dividing 4460 by 509, we get 8 with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 164899.8
Subtracting 4072 from 4460 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 10:
3880 divided by 509 is 7 with a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 164899.87
Deduct 3563 from 3880 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 11:
If we divide 3170 by 509, we get 6 and a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 164899.876
If we take 3054 away from 3170, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
509 goes into 1160 2 times with a remainder of 142.
The next digit of our result is 2. 
Result so far: 164899.8762
If we subtract 1018 from 1160, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 13:
When dividing 1420 by 509, we get 2 with a remainder of 402.
Use 2 as the next digit of our solution. 
Result so far: 164899.87622
If we take 1018 away from 1420, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final outcome is 164899.87622, with a leftover of 0.000402.
