We divide 78407750 by 70
We want to divide 78407750 by 70.

Going ahead to step 1:
If we divide 7 by 70, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 70

Let's proceed to step 2:
If we divide 78 by 70, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 70 from 78 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 70

Going ahead to step 3:
70 can be fit into 84 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 70 from 84 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 70

Step 4:
When dividing 140 by 70, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 112.0
If we subtract 140 from 140, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 70

Let's proceed to step 5:
When dividing 7 by 70, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 1120.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 70

On to step 6:
77 divided by 70 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 11201.0
Subtract 70 from 77 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 70

On to step 7:
70 can be fit into 75 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 112011.0
The remainder is 5 after subtracting 70 from 75.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 70

Moving on to step 8:
When dividing 50 by 70, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1120110.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1120110.7
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.

Advancing to step 10:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1120110.71
Deduct 70 from 100 and we're left 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.

On to step 11:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 1120110.714
Subtracting 280 from 300 leaves us 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.

Step 12:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 1120110.7142
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.

Advancing to step 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 1120110.71428
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.

Moving on to step 14:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1120110.714285
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.

On to step 15:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1120110.7142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 16:
If we divide 100 by 70, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1120110.71428571
If we subtract 70 from 100, we 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.

After the division, we end up with 1120110.71428571 and a remainder of 3e-08.
