We look at the division of 70519982 by 486 
Let's see how many times 486 fits into 70519982.

On to step 1:
7 divided by 486 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 486

Moving on to step 2:
70 divided by 486 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 486

Moving on to step 3:
When dividing 705 by 486, we get 1 with a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 486 from 705 and we're left with 219.
Append the next digit (1) from the dividend to 219 and continue with: 2191 / 486

Let's proceed to step 4:
486 can be fit into 2191 4 times, resulting in a remainder of 247.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1944 from 2191 leaves us with 247.
Grab the next digit (9) from the dividend, add it to 247, then carry on: 2479 / 486

Step 5:
486 goes into 2479 5 times with a remainder of 49.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 2430 from 2479 leaves us with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 486

Advancing to step 6:
486 goes into 499 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1451.0
If we take 486 away from 499, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 486

Going ahead to step 7:
When dividing 138 by 486, we get 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 14510.0
Subtract 0 from 138 to get 138.
Grab the next digit (2) from the dividend, add it to 138, then carry on: 1382 / 486

Step 8:
If we divide 1382 by 486, we get 2 and a remainder of 410.
Put 2 as the next digit of the answer. 
Result so far: 145102.0
If we subtract 972 from 1382, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 9:
4100 divided by 486 is 8 with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 145102.8
If we take 3888 away from 4100, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
When dividing 2120 by 486, we get 4 with a remainder of 176.
The next digit of our result is 4. 
Result so far: 145102.84
Subtract 1944 from 2120 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 11:
If we divide 1760 by 486, we get 3 and a remainder of 302.
The number 3 becomes the next digit in our result. 
Result so far: 145102.843
Subtracting 1458 from 1760 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 12:
3020 divided by 486 is 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 145102.8436
Subtracting 2916 from 3020 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
486 goes into 1040 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 145102.84362
If we take 972 away from 1040, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
680 divided by 486 is 1 with a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 145102.843621
Subtracting 486 from 680 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 15:
If we divide 1940 by 486, we get 3 and a remainder of 482.
The next digit of our result is 3. 
Result so far: 145102.8436213
The remainder is 482 after subtracting 1458 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 16:
If we divide 4820 by 486, we get 9 and a remainder of 446.
Use 9 as the next digit of our solution. 
Result so far: 145102.84362139
Subtract 4374 from 4820 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

In conclusion, the division gives 145102.84362139 with a balance of 4.46e-07.
