70660221 ÷ 389 
We want to divide 70660221 by 389.

Advancing to step 1:
When dividing 7 by 389, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 389

Moving on to step 2:
If we divide 70 by 389, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 389

On to step 3:
389 can be fit into 706 1 times, resulting in a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 389 from 706, we get 317.
Fetch the next digit (6) from the dividend, attach it to 317 and continue: 3176 / 389

Let's proceed to step 4:
If we divide 3176 by 389, we get 8 and a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3112 from 3176 to get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 389

Let's proceed to step 5:
The number 389 fits into 640 1 times, leaving a remainder of 251.
The next digit of our result is 1. 
Result so far: 181.0
Deduct 389 from 640 and we're left with 251.
Append the next digit (2) from the dividend to 251 and continue with: 2512 / 389

Step 6:
389 goes into 2512 6 times with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 1816.0
Subtracting 2334 from 2512 leaves us with 178.
Bring next digit (2) of the dividend behind the 178 and repeat the process: 1782 / 389

On to step 7:
1782 divided by 389 is 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 18164.0
Deduct 1556 from 1782 and we're left with 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 389

Advancing to step 8:
If we divide 2261 by 389, we get 5 and a remainder of 316.
Use 5 as the next digit of our solution. 
Result so far: 181645.0
If we take 1945 away from 2261, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 9:
The number 389 fits into 3160 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 181645.8
If we take 3112 away from 3160, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 389 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 181645.81
Deduct 389 from 480 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 11:
910 divided by 389 is 2 with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 181645.812
If we subtract 778 from 910, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 12:
When dividing 1320 by 389, we get 3 with a remainder of 153.
Record the quotient 3 as the next digit in the result. 
Result so far: 181645.8123
Deduct 1167 from 1320 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 13:
389 goes into 1530 3 times with a remainder of 363.
The next digit of our result is 3. 
Result so far: 181645.81233
If we take 1167 away from 1530, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

The quotient of the division is 181645.81233, and the remainder is 0.000363.
