78990 divided by 70 
We're looking to find how many times 70 goes into 78990.

Moving on to step 1:
The number 70 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 70

Going ahead to step 2:
If we divide 78 by 70, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 70 from 78 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 70

On to step 3:
70 can be fit into 89 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 70 from 89, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 70

Advancing to step 4:
70 can be fit into 199 2 times, resulting in a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 140 from 199 leaves us with 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 70

Step 5:
70 goes into 590 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 1128.0
Subtract 560 from 590 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.

On to step 6:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1128.4
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.

Let's proceed to step 7:
If we divide 200 by 70, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 1128.42
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1128.428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1128.4285
Deduct 350 from 400 and we're left 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.

Step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1128.42857
Subtract 490 from 500 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.

Going ahead to step 11:
100 divided by 70 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1128.428571
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.

Moving on to step 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1128.4285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 1128.42857142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 1128.42857142 with a balance of 6e-08.
