64430105 divided by 805 
We're looking to find how many times 805 goes into 64430105.

Let's proceed to step 1:
When dividing 6 by 805, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 805

Advancing to step 2:
805 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 805

Let's proceed to step 3:
805 goes into 644 0 times with a remainder of 644.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 644 to get 644.
Fetch the next digit (3) from the dividend, attach it to 644 and continue: 6443 / 805

Moving on to step 4:
805 can be fit into 6443 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6440 from 6443 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 805

Advancing to step 5:
If we divide 30 by 805, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 805

Let's proceed to step 6:
If we divide 301 by 805, we get 0 and a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 800.0
Subtracting 0 from 301 leaves us with 301.
Include the next digit (0) from the dividend after 301, then repeat: 3010 / 805

Step 7:
If we divide 3010 by 805, we get 3 and a remainder of 595.
Put 3 as the next digit of the answer. 
Result so far: 8003.0
Subtracting 2415 from 3010 leaves us with 595.
Include the next digit (5) from the dividend after 595, then repeat: 5955 / 805

Moving on to step 8:
The number 805 fits into 5955 7 times, leaving a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 80037.0
Subtract 5635 from 5955 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
When dividing 3200 by 805, we get 3 with a remainder of 785.
Record the quotient 3 as the next digit in the result. 
Result so far: 80037.3
Subtract 2415 from 3200 to get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Advancing to step 10:
The number 805 fits into 7850 9 times, leaving a remainder of 605.
Use 9 as the next digit of our solution. 
Result so far: 80037.39
If we take 7245 away from 7850, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 11:
When dividing 6050 by 805, we get 7 with a remainder of 415.
The number 7 becomes the next digit in our result. 
Result so far: 80037.397
Subtracting 5635 from 6050 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 12:
4150 divided by 805 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 80037.3975
If we take 4025 away from 4150, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 13:
The number 805 fits into 1250 1 times, leaving a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 80037.39751
Subtracting 805 from 1250 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 14:
4450 divided by 805 is 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 80037.397515
Deduct 4025 from 4450 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 15:
If we divide 4250 by 805, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 80037.3975155
Subtract 4025 from 4250 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 80037.3975155 with a balance of 2.25e-06.
