57790671 ÷ 870 
We want to divide 57790671 by 870.

Step 1:
The number 870 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 870

Step 2:
The number 870 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 870

Advancing to step 3:
577 divided by 870 is 0 with a remainder of 577.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 577, we get 577.
Take the next digit (9) from the dividend and append it to 577, then repeat: 5779 / 870

Step 4:
The number 870 fits into 5779 6 times, leaving a remainder of 559.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5220 from 5779 to get 559.
Append the next digit (0) from the dividend to 559 and continue with: 5590 / 870

Let's proceed to step 5:
The number 870 fits into 5590 6 times, leaving a remainder of 370.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 370 after subtracting 5220 from 5590.
Append the next digit (6) from the dividend to 370 and continue with: 3706 / 870

Let's proceed to step 6:
3706 divided by 870 is 4 with a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
If we subtract 3480 from 3706, we get 226.
Append the next digit (7) from the dividend to 226 and continue with: 2267 / 870

Let's proceed to step 7:
2267 divided by 870 is 2 with a remainder of 527.
Put 2 as the next digit of the answer. 
Result so far: 6642.0
Subtracting 1740 from 2267 leaves us with 527.
Bring next digit (1) of the dividend behind the 527 and repeat the process: 5271 / 870

Moving on to step 8:
5271 divided by 870 is 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 66426.0
Subtracting 5220 from 5271 leaves us with 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:
510 divided by 870 is 0 with a remainder of 510.
The next digit of our result is 0. 
Result so far: 66426.0
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
The number 870 fits into 5100 5 times, leaving a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 66426.05
Deduct 4350 from 5100 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 11:
When dividing 7500 by 870, we get 8 with a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 66426.058
Subtracting 6960 from 7500 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 12:
If we divide 5400 by 870, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 66426.0586
Subtracting 5220 from 5400 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
If we divide 1800 by 870, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 66426.05862
Subtract 1740 from 1800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 870 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 66426.05862
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 15:
The number 870 fits into 6000 6 times, leaving a remainder of 780.
The number 6 becomes the next digit in our result. 
Result so far: 66426.0586206
Subtract 5220 from 6000 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 16:
7800 divided by 870 is 8 with a remainder of 840.
Record the quotient 8 as the next digit in the result. 
Result so far: 66426.05862068
Subtract 6960 from 7800 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Our division results in 66426.05862068 with a remaining 8.4e-07.
