870053 ÷ 57 
Let's see how many times 57 fits into 870053.

Let's proceed to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 57

Step 2:
57 can be fit into 87 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 87 leaves us with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 57

Step 3:
57 goes into 300 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 285 from 300 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 57

Let's proceed to step 4:
When dividing 150 by 57, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtract 114 from 150 to get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 57

Going ahead to step 5:
57 goes into 365 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 1526.0
If we subtract 342 from 365, we get 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 57

Going ahead to step 6:
57 can be fit into 233 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 15264.0
If we take 228 away from 233, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
57 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 15264.0
Subtract 0 from 50 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.

Advancing to step 8:
57 can be fit into 500 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 15264.08
Subtracting 456 from 500 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
If we divide 440 by 57, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 15264.087
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
57 goes into 410 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 15264.0877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 15264.0877, with a leftover of 0.00011.
