15980243 divided by 70 
Our goal is to divide 15980243 by 70.

Going ahead to step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 70

Let's proceed to step 2:
The number 70 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 70

Moving on to step 3:
When dividing 159 by 70, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 140 from 159 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 70

Let's proceed to step 4:
198 divided by 70 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 140 away from 198, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 70

On to step 5:
The number 70 fits into 580 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 228.0
Subtracting 560 from 580 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 70

Let's proceed to step 6:
70 goes into 202 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 2282.0
Subtracting 140 from 202 leaves us with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 70

Let's proceed to step 7:
The number 70 fits into 624 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 22828.0
Deduct 560 from 624 and we're left with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 70

Advancing to step 8:
The number 70 fits into 643 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 228289.0
If we take 630 away from 643, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
70 goes into 130 1 times with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 228289.1
Deduct 70 from 130 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.

On to step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 228289.18
Deduct 560 from 600 and we're left 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.

Let's proceed to step 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 228289.185
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 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 228289.1857
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.

Step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 228289.18571
If we take 70 away from 100, we end up 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.

Going ahead to step 14:
300 divided by 70 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 228289.185714
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.

On to step 15:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 228289.1857142
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.

Let's proceed to step 16:
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: 228289.18571428
Subtracting 560 from 600 leaves us 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.

In conclusion, the division gives 228289.18571428 with a balance of 4e-08.
