We look at the division of 70521466 by 307 
Our goal is to divide 70521466 by 307.

On to step 1:
If we divide 7 by 307, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 307

Advancing to step 2:
When dividing 70 by 307, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 307

Moving on to step 3:
307 goes into 705 2 times with a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 614 from 705 and we're left with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 307

Going ahead to step 4:
If we divide 912 by 307, we get 2 and a remainder of 298.
The next digit of our result is 2. 
Result so far: 22.0
If we take 614 away from 912, we end up with 298.
Take the next digit (1) from the dividend and append it to 298, then repeat: 2981 / 307

Going ahead to step 5:
If we divide 2981 by 307, we get 9 and a remainder of 218.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we subtract 2763 from 2981, we get 218.
Bring next digit (4) of the dividend behind the 218 and repeat the process: 2184 / 307

Advancing to step 6:
If we divide 2184 by 307, we get 7 and a remainder of 35.
The next digit of our result is 7. 
Result so far: 2297.0
The remainder is 35 after subtracting 2149 from 2184.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 307

Advancing to step 7:
307 goes into 356 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 22971.0
Deduct 307 from 356 and we're left with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 307

Step 8:
If we divide 496 by 307, we get 1 and a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 229711.0
Deduct 307 from 496 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 9:
307 can be fit into 1890 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 229711.6
Subtract 1842 from 1890 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
If we divide 480 by 307, we get 1 and a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 229711.61
If we subtract 307 from 480, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 11:
307 can be fit into 1730 5 times, resulting in a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 229711.615
Subtract 1535 from 1730 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 12:
307 can be fit into 1950 6 times, resulting in a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 229711.6156
If we subtract 1842 from 1950, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 13:
307 can be fit into 1080 3 times, resulting in a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 229711.61563
Subtracting 921 from 1080 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 14:
If we divide 1590 by 307, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 229711.615635
If we subtract 1535 from 1590, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 15:
307 goes into 550 1 times with a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 229711.6156351
The remainder is 243 after subtracting 307 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 16:
If we divide 2430 by 307, we get 7 and a remainder of 281.
Put 7 as the next digit of the answer. 
Result so far: 229711.61563517
The remainder is 281 after subtracting 2149 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

In conclusion, the division gives 229711.61563517 with a balance of 2.81e-07.
