Let's divide 53171358 by 849
We want to figure out the number of times 53171358 can be divided by 849.

Going ahead to step 1:
The number 849 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 849

On to step 2:
The number 849 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 849

Step 3:
849 goes into 531 0 times with a remainder of 531.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 531, we get 531.
Bring next digit (7) of the dividend behind the 531 and repeat the process: 5317 / 849

Moving on to step 4:
849 goes into 5317 6 times with a remainder of 223.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5094 from 5317 to get 223.
Bring next digit (1) of the dividend behind the 223 and repeat the process: 2231 / 849

On to step 5:
When dividing 2231 by 849, we get 2 with a remainder of 533.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we take 1698 away from 2231, we end up with 533.
Bring next digit (3) of the dividend behind the 533 and repeat the process: 5333 / 849

Step 6:
The number 849 fits into 5333 6 times, leaving a remainder of 239.
Put 6 as the next digit of the answer. 
Result so far: 626.0
The remainder is 239 after subtracting 5094 from 5333.
Append the next digit (5) from the dividend to 239 and continue with: 2395 / 849

Moving on to step 7:
If we divide 2395 by 849, we get 2 and a remainder of 697.
The next digit of our result is 2. 
Result so far: 6262.0
If we take 1698 away from 2395, we end up with 697.
Fetch the next digit (8) from the dividend, attach it to 697 and continue: 6978 / 849

Advancing to step 8:
When dividing 6978 by 849, we get 8 with a remainder of 186.
The next digit of our result is 8. 
Result so far: 62628.0
Subtracting 6792 from 6978 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
When dividing 1860 by 849, we get 2 with a remainder of 162.
The next digit of our result is 2. 
Result so far: 62628.2
If we subtract 1698 from 1860, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 10:
849 can be fit into 1620 1 times, resulting in a remainder of 771.
Put 1 as the next digit of the answer. 
Result so far: 62628.21
The remainder is 771 after subtracting 849 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Advancing to step 11:
If we divide 7710 by 849, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 62628.219
Deduct 7641 from 7710 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
690 divided by 849 is 0 with a remainder of 690.
Write down 0 as next digit of the result. 
Result so far: 62628.219
Deduct 0 from 690 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 13:
849 goes into 6900 8 times with a remainder of 108.
The next digit of our result is 8. 
Result so far: 62628.21908
Subtract 6792 from 6900 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
849 can be fit into 1080 1 times, resulting in a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 62628.219081
Subtracting 849 from 1080 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 15:
849 goes into 2310 2 times with a remainder of 612.
The next digit of our result is 2. 
Result so far: 62628.2190812
If we take 1698 away from 2310, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 16:
If we divide 6120 by 849, we get 7 and a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 62628.21908127
Subtracting 5943 from 6120 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

After the division, we end up with 62628.21908127 and a remainder of 1.77e-07.
