70889109 ÷ 386 
Our goal is to divide 70889109 by 386.

Moving on to step 1:
When dividing 7 by 386, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 386

Advancing to step 2:
386 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 386

Step 3:
The number 386 fits into 708 1 times, leaving a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 386 from 708 leaves us with 322.
Fetch the next digit (8) from the dividend, attach it to 322 and continue: 3228 / 386

On to step 4:
The number 386 fits into 3228 8 times, leaving a remainder of 140.
The next digit of our result is 8. 
Result so far: 18.0
If we take 3088 away from 3228, we end up with 140.
Take the next digit (9) from the dividend and append it to 140, then repeat: 1409 / 386

Let's proceed to step 5:
If we divide 1409 by 386, we get 3 and a remainder of 251.
The next digit of our result is 3. 
Result so far: 183.0
Subtracting 1158 from 1409 leaves us with 251.
Grab the next digit (1) from the dividend, add it to 251, then carry on: 2511 / 386

Let's proceed to step 6:
386 goes into 2511 6 times with a remainder of 195.
The number 6 becomes the next digit in our result. 
Result so far: 1836.0
Subtracting 2316 from 2511 leaves us with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 386

Going ahead to step 7:
When dividing 1950 by 386, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 18365.0
If we take 1930 away from 1950, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 386

Moving on to step 8:
When dividing 209 by 386, we get 0 with a remainder of 209.
The next digit of our result is 0. 
Result so far: 183650.0
The remainder is 209 after subtracting 0 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
When dividing 2090 by 386, we get 5 with a remainder of 160.
The next digit of our result is 5. 
Result so far: 183650.5
If we subtract 1930 from 2090, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
If we divide 1600 by 386, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 183650.54
If we subtract 1544 from 1600, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
If we divide 560 by 386, we get 1 and a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 183650.541
Deduct 386 from 560 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 12:
1740 divided by 386 is 4 with a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 183650.5414
The remainder is 196 after subtracting 1544 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 13:
1960 divided by 386 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 183650.54145
Subtracting 1930 from 1960 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.

Advancing to step 14:
386 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 183650.54145
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
3000 divided by 386 is 7 with a remainder of 298.
Write down 7 as next digit of the result. 
Result so far: 183650.5414507
Subtracting 2702 from 3000 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 16:
386 can be fit into 2980 7 times, resulting in a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 183650.54145077
Deduct 2702 from 2980 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 183650.54145077, with a leftover of 2.78e-07.
