57870857 ÷ 650 
We want to figure out the number of times 57870857 can be divided by 650.

Step 1:
If we divide 5 by 650, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 650

Going ahead to step 2:
57 divided by 650 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 650

Step 3:
578 divided by 650 is 0 with a remainder of 578.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 578, we get 578.
Include the next digit (7) from the dividend after 578, then repeat: 5787 / 650

Moving on to step 4:
5787 divided by 650 is 8 with a remainder of 587.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 5200 from 5787 and we're left with 587.
Include the next digit (0) from the dividend after 587, then repeat: 5870 / 650

Going ahead to step 5:
5870 divided by 650 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 5850 from 5870 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 650

Going ahead to step 6:
650 can be fit into 208 0 times, resulting in a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 890.0
The remainder is 208 after subtracting 0 from 208.
Take the next digit (5) from the dividend and append it to 208, then repeat: 2085 / 650

Step 7:
When dividing 2085 by 650, we get 3 with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 8903.0
Subtracting 1950 from 2085 leaves us with 135.
Take the next digit (7) from the dividend and append it to 135, then repeat: 1357 / 650

Step 8:
If we divide 1357 by 650, we get 2 and a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 89032.0
If we take 1300 away from 1357, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
If we divide 570 by 650, we get 0 and a remainder of 570.
The next digit of our result is 0. 
Result so far: 89032.0
Subtracting 0 from 570 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 10:
If we divide 5700 by 650, we get 8 and a remainder of 500.
The next digit of our result is 8. 
Result so far: 89032.08
The remainder is 500 after subtracting 5200 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 11:
If we divide 5000 by 650, we get 7 and a remainder of 450.
Use 7 as the next digit of our solution. 
Result so far: 89032.087
If we subtract 4550 from 5000, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 12:
4500 divided by 650 is 6 with a remainder of 600.
The next digit of our result is 6. 
Result so far: 89032.0876
If we take 3900 away from 4500, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 13:
6000 divided by 650 is 9 with a remainder of 150.
Record the quotient 9 as the next digit in the result. 
Result so far: 89032.08769
Deduct 5850 from 6000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
When dividing 1500 by 650, we get 2 with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 89032.087692
If we subtract 1300 from 1500, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
The number 650 fits into 2000 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 89032.0876923
Subtract 1950 from 2000 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 16:
500 divided by 650 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 89032.0876923
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 89032.0876923 and a remainder of 5e-07.
