Let's divide 870594 by 57
We want to figure out the number of times 870594 can be divided by 57.

On 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
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 57

Advancing to step 2:
57 can be fit into 87 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
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

Going ahead to step 3:
57 goes into 300 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 285 from 300, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 57

Let's proceed to step 4:
When dividing 155 by 57, we get 2 with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtracting 114 from 155 leaves us with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 57

Advancing to step 5:
The number 57 fits into 419 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 1527.0
Deduct 399 from 419 and we're left with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 57

Advancing to step 6:
If we divide 204 by 57, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 15273.0
Deduct 171 from 204 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
330 divided by 57 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15273.5
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
When dividing 450 by 57, we get 7 with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 15273.57
If we subtract 399 from 450, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 15273.578
Deduct 456 from 510 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
57 goes into 540 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 15273.5789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
If we divide 270 by 57, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 15273.57894
If we take 228 away from 270, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
57 can be fit into 420 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 15273.578947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
When dividing 210 by 57, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 15273.5789473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 14:
If we divide 390 by 57, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 15273.57894736
Subtract 342 from 390 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 15273.57894736 with a remainder of 4.8e-08.
