We look at the division of 69921234 by 312 
We want to divide 69921234 by 312.

On to step 1:
312 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 312

On to step 2:
312 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 312

Let's proceed to step 3:
312 can be fit into 699 2 times, resulting in a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 624 away from 699, we end up with 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 312

On to step 4:
752 divided by 312 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 624 from 752, we get 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 312

Advancing to step 5:
1281 divided by 312 is 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 224.0
If we subtract 1248 from 1281, we get 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 312

Advancing to step 6:
If we divide 332 by 312, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 2241.0
Subtract 312 from 332 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 312

On to step 7:
203 divided by 312 is 0 with a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 22410.0
The remainder is 203 after subtracting 0 from 203.
Bring next digit (4) of the dividend behind the 203 and repeat the process: 2034 / 312

On to step 8:
312 can be fit into 2034 6 times, resulting in a remainder of 162.
Use 6 as the next digit of our solution. 
Result so far: 224106.0
If we subtract 1872 from 2034, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 9:
312 goes into 1620 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 224106.5
If we take 1560 away from 1620, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 312 fits into 600 1 times, leaving a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 224106.51
Deduct 312 from 600 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 11:
312 goes into 2880 9 times with a remainder of 72.
The next digit of our result is 9. 
Result so far: 224106.519
If we subtract 2808 from 2880, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
When dividing 720 by 312, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 224106.5192
The remainder is 96 after subtracting 624 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
312 goes into 960 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 224106.51923
If we take 936 away from 960, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
If we divide 240 by 312, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 224106.51923
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
The number 312 fits into 2400 7 times, leaving a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 224106.5192307
If we subtract 2184 from 2400, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 16:
2160 divided by 312 is 6 with a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 224106.51923076
The remainder is 288 after subtracting 1872 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 224106.51923076 and a remainder of 2.88e-07.
