We look at the division of 53750421 by 631 
We're looking to find how many times 631 goes into 53750421.

Let's proceed to step 1:
If we divide 5 by 631, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 631

Going ahead to step 2:
The number 631 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 631

Let's proceed to step 3:
If we divide 537 by 631, we get 0 and a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 537 leaves us with 537.
Take the next digit (5) from the dividend and append it to 537, then repeat: 5375 / 631

Moving on to step 4:
If we divide 5375 by 631, we get 8 and a remainder of 327.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 5048 from 5375 leaves us with 327.
Grab the next digit (0) from the dividend, add it to 327, then carry on: 3270 / 631

Going ahead to step 5:
631 goes into 3270 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 85.0
If we take 3155 away from 3270, we end up with 115.
Include the next digit (4) from the dividend after 115, then repeat: 1154 / 631

Let's proceed to step 6:
631 goes into 1154 1 times with a remainder of 523.
Use 1 as the next digit of our solution. 
Result so far: 851.0
If we subtract 631 from 1154, we get 523.
Grab the next digit (2) from the dividend, add it to 523, then carry on: 5232 / 631

Let's proceed to step 7:
631 can be fit into 5232 8 times, resulting in a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 8518.0
The remainder is 184 after subtracting 5048 from 5232.
Bring next digit (1) of the dividend behind the 184 and repeat the process: 1841 / 631

Step 8:
The number 631 fits into 1841 2 times, leaving a remainder of 579.
The next digit of our result is 2. 
Result so far: 85182.0
Subtract 1262 from 1841 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
631 goes into 5790 9 times with a remainder of 111.
Write down 9 as next digit of the result. 
Result so far: 85182.9
If we take 5679 away from 5790, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 10:
631 can be fit into 1110 1 times, resulting in a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 85182.91
If we take 631 away from 1110, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 11:
631 goes into 4790 7 times with a remainder of 373.
Use 7 as the next digit of our solution. 
Result so far: 85182.917
Subtracting 4417 from 4790 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 12:
The number 631 fits into 3730 5 times, leaving a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 85182.9175
Subtract 3155 from 3730 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 13:
5750 divided by 631 is 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 85182.91759
The remainder is 71 after subtracting 5679 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
When dividing 710 by 631, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 85182.917591
If we subtract 631 from 710, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 15:
631 goes into 790 1 times with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 85182.9175911
The remainder is 159 after subtracting 631 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

After the division, we end up with 85182.9175911 and a remainder of 1.59e-06.
