We look at the division of 64437797 by 180 
Our goal is to divide 64437797 by 180.

Going ahead to step 1:
180 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 180

Let's proceed to step 2:
The number 180 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 180

Let's proceed to step 3:
When dividing 644 by 180, we get 3 with a remainder of 104.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 540 from 644, we get 104.
Include the next digit (3) from the dividend after 104, then repeat: 1043 / 180

Advancing to step 4:
If we divide 1043 by 180, we get 5 and a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 900 from 1043 and we're left with 143.
Take the next digit (7) from the dividend and append it to 143, then repeat: 1437 / 180

Moving on to step 5:
If we divide 1437 by 180, we get 7 and a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 357.0
If we take 1260 away from 1437, we end up with 177.
Take the next digit (7) from the dividend and append it to 177, then repeat: 1777 / 180

Let's proceed to step 6:
When dividing 1777 by 180, we get 9 with a remainder of 157.
The number 9 becomes the next digit in our result. 
Result so far: 3579.0
If we take 1620 away from 1777, we end up with 157.
Include the next digit (9) from the dividend after 157, then repeat: 1579 / 180

Going ahead to step 7:
1579 divided by 180 is 8 with a remainder of 139.
The number 8 becomes the next digit in our result. 
Result so far: 35798.0
Subtracting 1440 from 1579 leaves us with 139.
Take the next digit (7) from the dividend and append it to 139, then repeat: 1397 / 180

Let's proceed to step 8:
180 goes into 1397 7 times with a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 357987.0
If we take 1260 away from 1397, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 9:
When dividing 1370 by 180, we get 7 with a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 357987.7
Deduct 1260 from 1370 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 180, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 357987.76
Subtract 1080 from 1100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
180 goes into 200 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 357987.761
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
180 goes into 200 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 357987.7611
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 357987.7611, with a leftover of 0.0002.
