We look at the division of 13561971 by 637 
We want to figure out the number of times 13561971 can be divided by 637.

Let's proceed to step 1:
The number 637 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 637

Going ahead to step 2:
637 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 637

Step 3:
637 goes into 135 0 times with a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 135 leaves us with 135.
Bring next digit (6) of the dividend behind the 135 and repeat the process: 1356 / 637

On to step 4:
637 goes into 1356 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1274 from 1356 leaves us with 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 637

On to step 5:
637 can be fit into 821 1 times, resulting in a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 637 from 821, we get 184.
Include the next digit (9) from the dividend after 184, then repeat: 1849 / 637

Let's proceed to step 6:
When dividing 1849 by 637, we get 2 with a remainder of 575.
The next digit of our result is 2. 
Result so far: 212.0
Subtract 1274 from 1849 to get 575.
Grab the next digit (7) from the dividend, add it to 575, then carry on: 5757 / 637

Let's proceed to step 7:
When dividing 5757 by 637, we get 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 2129.0
Subtract 5733 from 5757 to get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 637

Moving on to step 8:
If we divide 241 by 637, we get 0 and a remainder of 241.
Record the quotient 0 as the next digit in the result. 
Result so far: 21290.0
Subtracting 0 from 241 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 9:
If we divide 2410 by 637, we get 3 and a remainder of 499.
The next digit of our result is 3. 
Result so far: 21290.3
Subtract 1911 from 2410 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Let's proceed to step 10:
637 can be fit into 4990 7 times, resulting in a remainder of 531.
Record the quotient 7 as the next digit in the result. 
Result so far: 21290.37
If we take 4459 away from 4990, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 11:
637 can be fit into 5310 8 times, resulting in a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 21290.378
Subtracting 5096 from 5310 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 12:
The number 637 fits into 2140 3 times, leaving a remainder of 229.
The number 3 becomes the next digit in our result. 
Result so far: 21290.3783
If we take 1911 away from 2140, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 13:
637 can be fit into 2290 3 times, resulting in a remainder of 379.
Write down 3 as next digit of the result. 
Result so far: 21290.37833
The remainder is 379 after subtracting 1911 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

The quotient of the division is 21290.37833, and the remainder is 0.000379.
