We're dividing 39385151 by 70 
We want to figure out the number of times 39385151 can be divided by 70.

On to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 70

On to step 2:
The number 70 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 70

On to step 3:
393 divided by 70 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 350 from 393 leaves us with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 70

Advancing to step 4:
70 goes into 438 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 420 from 438, we get 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 70

Let's proceed to step 5:
185 divided by 70 is 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 562.0
Subtracting 140 from 185 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 70

Moving on to step 6:
If we divide 451 by 70, we get 6 and a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 5626.0
Subtract 420 from 451 to get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 70

On to step 7:
70 goes into 315 4 times with a remainder of 35.
The next digit of our result is 4. 
Result so far: 56264.0
Subtract 280 from 315 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 70

Advancing to step 8:
70 can be fit into 351 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 562645.0
If we subtract 350 from 351, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 70 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 562645.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 562645.01
Subtract 70 from 100 to get 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 11:
If we divide 300 by 70, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 562645.014
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
70 goes into 200 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 562645.0142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
70 goes into 600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 562645.01428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
If we divide 400 by 70, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 562645.014285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 562645.0142857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
70 goes into 100 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 562645.01428571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 562645.01428571 with a balance of 3e-08.
