70864841 divided by 307 
Our goal is to divide 70864841 by 307.

Advancing to step 1:
If we divide 7 by 307, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 307

On to step 2:
If we divide 70 by 307, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 307

On to step 3:
When dividing 708 by 307, we get 2 with a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 614 from 708 and we're left with 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 307

Moving on to step 4:
If we divide 946 by 307, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 921 from 946 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 307

Step 5:
254 divided by 307 is 0 with a remainder of 254.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Deduct 0 from 254 and we're left with 254.
Include the next digit (8) from the dividend after 254, then repeat: 2548 / 307

Step 6:
2548 divided by 307 is 8 with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 2308.0
Deduct 2456 from 2548 and we're left with 92.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 307

Advancing to step 7:
307 goes into 924 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 23083.0
Deduct 921 from 924 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 307

Advancing to step 8:
When dividing 31 by 307, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 230830.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
307 goes into 310 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 230830.1
If we subtract 307 from 310, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
30 divided by 307 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 230830.1
Subtracting 0 from 30 leaves us 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.

Let's proceed to step 11:
The number 307 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 230830.1
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 230830.1, with a leftover of 0.03.
