858613 divided by 57 
Let's see how many times 57 fits into 858613.

Let's proceed to step 1:
8 divided by 57 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 57

Advancing to step 2:
When dividing 85 by 57, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 85, we get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 57

Step 3:
57 can be fit into 288 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 285 from 288 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 57

Step 4:
When dividing 36 by 57, we get 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtracting 0 from 36 leaves us with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 57

On to step 5:
When dividing 361 by 57, we get 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 1506.0
Subtracting 342 from 361 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 57

Step 6:
When dividing 193 by 57, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 15063.0
If we take 171 away from 193, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
57 goes into 220 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 15063.3
Subtract 171 from 220 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
When dividing 490 by 57, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 15063.38
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 57, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 15063.385
If we take 285 away from 340, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
If we divide 550 by 57, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 15063.3859
If we take 513 away from 550, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 11:
If we divide 370 by 57, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 15063.38596
Subtracting 342 from 370 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
57 goes into 280 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 15063.385964
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
If we divide 520 by 57, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 15063.3859649
Subtract 513 from 520 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
57 can be fit into 70 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 15063.38596491
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 15063.38596491 and a remainder of 1.3e-08.
