Let's divide 8621977 by 870
Our goal is to divide 8621977 by 870.

Advancing to step 1:
If we divide 8 by 870, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 870

Step 2:
86 divided by 870 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (2) from the dividend, add it to 86, then carry on: 862 / 870

Let's proceed to step 3:
The number 870 fits into 862 0 times, leaving a remainder of 862.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 862, we end up with 862.
Bring next digit (1) of the dividend behind the 862 and repeat the process: 8621 / 870

Step 4:
8621 divided by 870 is 9 with a remainder of 791.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7830 from 8621, we get 791.
Grab the next digit (9) from the dividend, add it to 791, then carry on: 7919 / 870

Moving on to step 5:
7919 divided by 870 is 9 with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 7830 from 7919, we get 89.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 870

Let's proceed to step 6:
870 goes into 897 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 991.0
Deduct 870 from 897 and we're left with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 870

Moving on to step 7:
When dividing 277 by 870, we get 0 with a remainder of 277.
Use 0 as the next digit of our solution. 
Result so far: 9910.0
Subtract 0 from 277 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 8:
The number 870 fits into 2770 3 times, leaving a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 9910.3
Deduct 2610 from 2770 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
1600 divided by 870 is 1 with a remainder of 730.
Use 1 as the next digit of our solution. 
Result so far: 9910.31
Deduct 870 from 1600 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 10:
If we divide 7300 by 870, we get 8 and a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 9910.318
If we subtract 6960 from 7300, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
If we divide 3400 by 870, we get 3 and a remainder of 790.
The number 3 becomes the next digit in our result. 
Result so far: 9910.3183
Subtract 2610 from 3400 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 12:
The number 870 fits into 7900 9 times, leaving a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 9910.31839
Subtract 7830 from 7900 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.

Step 13:
870 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 9910.31839
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 14:
870 goes into 7000 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 9910.3183908
If we take 6960 away from 7000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
870 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 9910.3183908
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 9910.3183908 with a balance of 4e-07.
