10349668 ÷ 870 
We want to divide 10349668 by 870.

Going ahead to step 1:
When dividing 1 by 870, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 870

On to step 2:
10 divided by 870 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 870

Moving on to step 3:
The number 870 fits into 103 0 times, leaving a remainder of 103.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 103, we end up with 103.
Fetch the next digit (4) from the dividend, attach it to 103 and continue: 1034 / 870

Advancing to step 4:
1034 divided by 870 is 1 with a remainder of 164.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 870 from 1034 to get 164.
Fetch the next digit (9) from the dividend, attach it to 164 and continue: 1649 / 870

Going ahead to step 5:
When dividing 1649 by 870, we get 1 with a remainder of 779.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 779 after subtracting 870 from 1649.
Fetch the next digit (6) from the dividend, attach it to 779 and continue: 7796 / 870

Step 6:
If we divide 7796 by 870, we get 8 and a remainder of 836.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtract 6960 from 7796 to get 836.
Fetch the next digit (6) from the dividend, attach it to 836 and continue: 8366 / 870

Step 7:
870 can be fit into 8366 9 times, resulting in a remainder of 536.
Record the quotient 9 as the next digit in the result. 
Result so far: 1189.0
Subtracting 7830 from 8366 leaves us with 536.
Fetch the next digit (8) from the dividend, attach it to 536 and continue: 5368 / 870

Advancing to step 8:
5368 divided by 870 is 6 with a remainder of 148.
Write down 6 as next digit of the result. 
Result so far: 11896.0
The remainder is 148 after subtracting 5220 from 5368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
1480 divided by 870 is 1 with a remainder of 610.
Put 1 as the next digit of the answer. 
Result so far: 11896.1
Subtract 870 from 1480 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
The number 870 fits into 6100 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11896.17
If we take 6090 away from 6100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
870 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 11896.17
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
1000 divided by 870 is 1 with a remainder of 130.
The next digit of our result is 1. 
Result so far: 11896.1701
If we take 870 away from 1000, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 13:
The number 870 fits into 1300 1 times, leaving a remainder of 430.
The number 1 becomes the next digit in our result. 
Result so far: 11896.17011
Subtracting 870 from 1300 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

After the division, we end up with 11896.17011 and a remainder of 0.00043.
