57849986 divided by 647 
Our goal is to divide 57849986 by 647.

Moving on to step 1:
If we divide 5 by 647, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 647

Moving on to step 2:
647 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 647

Moving on to step 3:
647 goes into 578 0 times with a remainder of 578.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 578 after subtracting 0 from 578.
Append the next digit (4) from the dividend to 578 and continue with: 5784 / 647

Going ahead to step 4:
The number 647 fits into 5784 8 times, leaving a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5176 from 5784 and we're left with 608.
Take the next digit (9) from the dividend and append it to 608, then repeat: 6089 / 647

Step 5:
If we divide 6089 by 647, we get 9 and a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 5823 from 6089, we get 266.
Grab the next digit (9) from the dividend, add it to 266, then carry on: 2669 / 647

Moving on to step 6:
If we divide 2669 by 647, we get 4 and a remainder of 81.
The next digit of our result is 4. 
Result so far: 894.0
If we take 2588 away from 2669, we end up with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 647

Moving on to step 7:
If we divide 818 by 647, we get 1 and a remainder of 171.
The next digit of our result is 1. 
Result so far: 8941.0
If we subtract 647 from 818, we get 171.
Fetch the next digit (6) from the dividend, attach it to 171 and continue: 1716 / 647

Moving on to step 8:
If we divide 1716 by 647, we get 2 and a remainder of 422.
Write down 2 as next digit of the result. 
Result so far: 89412.0
Deduct 1294 from 1716 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 9:
4220 divided by 647 is 6 with a remainder of 338.
Use 6 as the next digit of our solution. 
Result so far: 89412.6
Subtract 3882 from 4220 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
When dividing 3380 by 647, we get 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 89412.65
If we subtract 3235 from 3380, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 11:
647 goes into 1450 2 times with a remainder of 156.
The next digit of our result is 2. 
Result so far: 89412.652
Subtract 1294 from 1450 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 12:
647 can be fit into 1560 2 times, resulting in a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 89412.6522
Subtracting 1294 from 1560 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final result is 89412.6522 with a remainder of 0.00266.
