We're dividing 870243 by 69 
Let's see how many times 69 fits into 870243.

On to step 1:
69 goes into 8 0 times 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.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 69

Going ahead to step 2:
The number 69 fits into 87 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 69 from 87 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 69

Moving on to step 3:
If we divide 180 by 69, we get 2 and a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 138 from 180 to get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 69

Let's proceed to step 4:
If we divide 422 by 69, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtract 414 from 422 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 69

Advancing to step 5:
84 divided by 69 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1261.0
The remainder is 15 after subtracting 69 from 84.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 69

Advancing to step 6:
69 goes into 153 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 12612.0
If we take 138 away from 153, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
69 can be fit into 150 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12612.2
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 69, we get 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 12612.21
Deduct 69 from 120 and we're left 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:
69 can be fit into 510 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 12612.217
The remainder is 27 after subtracting 483 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
69 goes into 270 3 times with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 12612.2173
If we subtract 207 from 270, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 11:
69 goes into 630 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 12612.21739
The remainder is 9 after subtracting 621 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 69, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 12612.217391
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
The number 69 fits into 210 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 12612.2173913
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
30 divided by 69 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 12612.2173913
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 12612.2173913 and a remainder of 3e-08.
