We look at the division of 637749 by 4 
We want to divide 637749 by 4.

Going ahead to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

Let's proceed to step 2:
If we divide 23 by 4, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 20 from 23, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Advancing to step 3:
4 goes into 37 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 36 away from 37, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

On to step 4:
When dividing 17 by 4, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1594.0
Deduct 16 from 17 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Let's proceed to step 5:
14 divided by 4 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 15943.0
Subtracting 12 from 14 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 4

Step 6:
4 can be fit into 29 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 159437.0
Deduct 28 from 29 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 4 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 159437.2
If we take 8 away from 10, we end up 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.

Let's proceed to step 8:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 159437.25
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 159437.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 159437.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 159437.25 with a balance of 0.0.
