69908142 ÷ 486 
We want to divide 69908142 by 486.

Let's proceed to step 1:
486 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 486

On to step 2:
486 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 486

Going ahead to step 3:
When dividing 699 by 486, we get 1 with a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 486 from 699 and we're left with 213.
Take the next digit (0) from the dividend and append it to 213, then repeat: 2130 / 486

Moving on to step 4:
When dividing 2130 by 486, we get 4 with a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1944 from 2130, we get 186.
Bring next digit (8) of the dividend behind the 186 and repeat the process: 1868 / 486

Going ahead to step 5:
486 can be fit into 1868 3 times, resulting in a remainder of 410.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
The remainder is 410 after subtracting 1458 from 1868.
Include the next digit (1) from the dividend after 410, then repeat: 4101 / 486

Moving on to step 6:
486 can be fit into 4101 8 times, resulting in a remainder of 213.
Use 8 as the next digit of our solution. 
Result so far: 1438.0
Deduct 3888 from 4101 and we're left with 213.
Include the next digit (4) from the dividend after 213, then repeat: 2134 / 486

On to step 7:
When dividing 2134 by 486, we get 4 with a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 14384.0
Subtracting 1944 from 2134 leaves us with 190.
Append the next digit (2) from the dividend to 190 and continue with: 1902 / 486

On to step 8:
486 goes into 1902 3 times with a remainder of 444.
Write down 3 as next digit of the result. 
Result so far: 143843.0
If we take 1458 away from 1902, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 9:
4440 divided by 486 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 143843.9
Subtracting 4374 from 4440 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
The number 486 fits into 660 1 times, leaving a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 143843.91
Subtract 486 from 660 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
1740 divided by 486 is 3 with a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 143843.913
If we subtract 1458 from 1740, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 12:
When dividing 2820 by 486, we get 5 with a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 143843.9135
Subtract 2430 from 2820 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
486 goes into 3900 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 143843.91358
Subtracting 3888 from 3900 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
486 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 143843.91358
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
When dividing 1200 by 486, we get 2 with a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 143843.9135802
If we take 972 away from 1200, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 16:
2280 divided by 486 is 4 with a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 143843.91358024
The remainder is 336 after subtracting 1944 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 143843.91358024 with a balance of 3.36e-07.
