Let's divide 86641039 by 53
Our goal is to divide 86641039 by 53.

On to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 53

Going ahead to step 2:
The number 53 fits into 86 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 53 away from 86, we end up with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 53

Advancing to step 3:
53 can be fit into 336 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 318 away from 336, we end up with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 53

On to step 4:
If we divide 184 by 53, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we take 159 away from 184, we end up with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 53

Step 5:
53 can be fit into 251 4 times, resulting in a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 1634.0
The remainder is 39 after subtracting 212 from 251.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 53

Going ahead to step 6:
390 divided by 53 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 16347.0
Deduct 371 from 390 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 53

Going ahead to step 7:
When dividing 193 by 53, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 163473.0
Subtract 159 from 193 to get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 53

Going ahead to step 8:
When dividing 349 by 53, we get 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 1634736.0
If we subtract 318 from 349, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
53 goes into 310 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1634736.5
Subtract 265 from 310 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
53 can be fit into 450 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1634736.58
If we take 424 away from 450, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 53 fits into 260 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 1634736.584
If we subtract 212 from 260, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 53, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1634736.5849
Deduct 477 from 480 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 53 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1634736.5849
The remainder is 30 after subtracting 0 from 30.
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 14:
When dividing 300 by 53, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1634736.584905
Subtracting 265 from 300 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
When dividing 350 by 53, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1634736.5849056
Subtract 318 from 350 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 53, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1634736.58490566
Deduct 318 from 320 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 1634736.58490566 with a remaining 2e-09.
