We're dividing 86840783 by 605 
We want to divide 86840783 by 605.

Let's proceed to step 1:
605 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 605

Step 2:
When dividing 86 by 605, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 605

On to step 3:
605 can be fit into 868 1 times, resulting in a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 605 from 868 leaves us with 263.
Grab the next digit (4) from the dividend, add it to 263, then carry on: 2634 / 605

Step 4:
2634 divided by 605 is 4 with a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2420 from 2634 and we're left with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 605

Step 5:
605 goes into 2140 3 times with a remainder of 325.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 1815 from 2140 to get 325.
Bring next digit (7) of the dividend behind the 325 and repeat the process: 3257 / 605

Moving on to step 6:
605 can be fit into 3257 5 times, resulting in a remainder of 232.
Write down 5 as next digit of the result. 
Result so far: 1435.0
If we take 3025 away from 3257, we end up with 232.
Fetch the next digit (8) from the dividend, attach it to 232 and continue: 2328 / 605

On to step 7:
605 can be fit into 2328 3 times, resulting in a remainder of 513.
Put 3 as the next digit of the answer. 
Result so far: 14353.0
Deduct 1815 from 2328 and we're left with 513.
Grab the next digit (3) from the dividend, add it to 513, then carry on: 5133 / 605

Advancing to step 8:
605 can be fit into 5133 8 times, resulting in a remainder of 293.
Use 8 as the next digit of our solution. 
Result so far: 143538.0
The remainder is 293 after subtracting 4840 from 5133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 9:
605 goes into 2930 4 times with a remainder of 510.
The number 4 becomes the next digit in our result. 
Result so far: 143538.4
The remainder is 510 after subtracting 2420 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
605 goes into 5100 8 times with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 143538.48
Deduct 4840 from 5100 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
605 goes into 2600 4 times with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 143538.484
If we take 2420 away from 2600, we end up 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.

Going ahead to step 12:
1800 divided by 605 is 2 with a remainder of 590.
The number 2 becomes the next digit in our result. 
Result so far: 143538.4842
If we subtract 1210 from 1800, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 13:
605 goes into 5900 9 times with a remainder of 455.
Record the quotient 9 as the next digit in the result. 
Result so far: 143538.48429
The remainder is 455 after subtracting 5445 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 14:
When dividing 4550 by 605, we get 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 143538.484297
If we take 4235 away from 4550, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 15:
3150 divided by 605 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 143538.4842975
If we take 3025 away from 3150, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 16:
The number 605 fits into 1250 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 143538.48429752
If we take 1210 away from 1250, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 143538.48429752, and the remainder is 4e-08.
