64405025 ÷ 860 
Let's see how many times 860 fits into 64405025.

Advancing to step 1:
If we divide 6 by 860, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 860

Going ahead to step 2:
If we divide 64 by 860, we get 0 and 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.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 860

Moving on to step 3:
644 divided by 860 is 0 with a remainder of 644.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 644, we end up with 644.
Bring next digit (0) of the dividend behind the 644 and repeat the process: 6440 / 860

Let's proceed to step 4:
If we divide 6440 by 860, we get 7 and a remainder of 420.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6020 away from 6440, we end up with 420.
Grab the next digit (5) from the dividend, add it to 420, then carry on: 4205 / 860

On to step 5:
If we divide 4205 by 860, we get 4 and a remainder of 765.
The next digit of our result is 4. 
Result so far: 74.0
If we take 3440 away from 4205, we end up with 765.
Take the next digit (0) from the dividend and append it to 765, then repeat: 7650 / 860

Advancing to step 6:
When dividing 7650 by 860, we get 8 with a remainder of 770.
The next digit of our result is 8. 
Result so far: 748.0
Subtract 6880 from 7650 to get 770.
Grab the next digit (2) from the dividend, add it to 770, then carry on: 7702 / 860

On to step 7:
The number 860 fits into 7702 8 times, leaving a remainder of 822.
The next digit of our result is 8. 
Result so far: 7488.0
If we take 6880 away from 7702, we end up with 822.
Fetch the next digit (5) from the dividend, attach it to 822 and continue: 8225 / 860

On to step 8:
860 can be fit into 8225 9 times, resulting in a remainder of 485.
The number 9 becomes the next digit in our result. 
Result so far: 74889.0
If we take 7740 away from 8225, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 9:
4850 divided by 860 is 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 74889.5
If we subtract 4300 from 4850, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
When dividing 5500 by 860, we get 6 with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 74889.56
Subtracting 5160 from 5500 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
860 goes into 3400 3 times with a remainder of 820.
Put 3 as the next digit of the answer. 
Result so far: 74889.563
The remainder is 820 after subtracting 2580 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 12:
If we divide 8200 by 860, we get 9 and a remainder of 460.
Use 9 as the next digit of our solution. 
Result so far: 74889.5639
Deduct 7740 from 8200 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 13:
When dividing 4600 by 860, we get 5 with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 74889.56395
The remainder is 300 after subtracting 4300 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 14:
3000 divided by 860 is 3 with a remainder of 420.
Record the quotient 3 as the next digit in the result. 
Result so far: 74889.563953
Subtracting 2580 from 3000 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 15:
If we divide 4200 by 860, we get 4 and a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 74889.5639534
Deduct 3440 from 4200 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 16:
7600 divided by 860 is 8 with a remainder of 720.
The next digit of our result is 8. 
Result so far: 74889.56395348
If we subtract 6880 from 7600, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 74889.56395348 and a remainder of 7.2e-07.
