57859331 ÷ 670 
We want to figure out the number of times 57859331 can be divided by 670.

Step 1:
When dividing 5 by 670, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 670

Let's proceed to step 2:
670 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 670

Advancing to step 3:
578 divided by 670 is 0 with a remainder of 578.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 578 and we're left with 578.
Grab the next digit (5) from the dividend, add it to 578, then carry on: 5785 / 670

On to step 4:
When dividing 5785 by 670, we get 8 with a remainder of 425.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 425 after subtracting 5360 from 5785.
Take the next digit (9) from the dividend and append it to 425, then repeat: 4259 / 670

On to step 5:
670 can be fit into 4259 6 times, resulting in a remainder of 239.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 4020 away from 4259, we end up with 239.
Bring next digit (3) of the dividend behind the 239 and repeat the process: 2393 / 670

Let's proceed to step 6:
The number 670 fits into 2393 3 times, leaving a remainder of 383.
Write down 3 as next digit of the result. 
Result so far: 863.0
Subtract 2010 from 2393 to get 383.
Grab the next digit (3) from the dividend, add it to 383, then carry on: 3833 / 670

Let's proceed to step 7:
The number 670 fits into 3833 5 times, leaving a remainder of 483.
The next digit of our result is 5. 
Result so far: 8635.0
Subtracting 3350 from 3833 leaves us with 483.
Bring next digit (1) of the dividend behind the 483 and repeat the process: 4831 / 670

Let's proceed to step 8:
The number 670 fits into 4831 7 times, leaving a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 86357.0
If we subtract 4690 from 4831, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
The number 670 fits into 1410 2 times, leaving a remainder of 70.
The next digit of our result is 2. 
Result so far: 86357.2
Subtract 1340 from 1410 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
When dividing 700 by 670, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 86357.21
The remainder is 30 after subtracting 670 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 670 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 86357.21
Subtracting 0 from 300 leaves us with 300.
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 12:
670 can be fit into 3000 4 times, resulting in a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 86357.2104
The remainder is 320 after subtracting 2680 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
670 goes into 3200 4 times with a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 86357.21044
The remainder is 520 after subtracting 2680 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 86357.21044 with a remaining 0.00052.
