We're dividing 53861141 by 631 
Our goal is to divide 53861141 by 631.

Let's proceed to step 1:
If we divide 5 by 631, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 631

Advancing to step 2:
631 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 631

Advancing to step 3:
When dividing 538 by 631, we get 0 with a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 538 after subtracting 0 from 538.
Bring next digit (6) of the dividend behind the 538 and repeat the process: 5386 / 631

Going ahead to step 4:
5386 divided by 631 is 8 with a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5048 away from 5386, we end up with 338.
Include the next digit (1) from the dividend after 338, then repeat: 3381 / 631

Moving on to step 5:
The number 631 fits into 3381 5 times, leaving a remainder of 226.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we take 3155 away from 3381, we end up with 226.
Append the next digit (1) from the dividend to 226 and continue with: 2261 / 631

Step 6:
631 can be fit into 2261 3 times, resulting in a remainder of 368.
Write down 3 as next digit of the result. 
Result so far: 853.0
If we take 1893 away from 2261, we end up with 368.
Grab the next digit (4) from the dividend, add it to 368, then carry on: 3684 / 631

Let's proceed to step 7:
The number 631 fits into 3684 5 times, leaving a remainder of 529.
Put 5 as the next digit of the answer. 
Result so far: 8535.0
Subtracting 3155 from 3684 leaves us with 529.
Fetch the next digit (1) from the dividend, attach it to 529 and continue: 5291 / 631

Advancing to step 8:
631 can be fit into 5291 8 times, resulting in a remainder of 243.
Use 8 as the next digit of our solution. 
Result so far: 85358.0
Deduct 5048 from 5291 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 9:
631 goes into 2430 3 times with a remainder of 537.
Put 3 as the next digit of the answer. 
Result so far: 85358.3
If we take 1893 away from 2430, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 10:
If we divide 5370 by 631, we get 8 and a remainder of 322.
The next digit of our result is 8. 
Result so far: 85358.38
Subtract 5048 from 5370 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 11:
631 can be fit into 3220 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 85358.385
If we take 3155 away from 3220, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
If we divide 650 by 631, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 85358.3851
If we take 631 away from 650, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
When dividing 190 by 631, we get 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 85358.3851
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
631 can be fit into 1900 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 85358.385103
Subtract 1893 from 1900 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
If we divide 70 by 631, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 85358.385103
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
631 can be fit into 700 1 times, resulting in a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 85358.38510301
If we take 631 away from 700, we end up 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.

The final outcome is 85358.38510301, with a leftover of 6.9e-08.
