69086904 ÷ 142 
Let's see how many times 142 fits into 69086904.

Advancing to step 1:
When dividing 6 by 142, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 142

Moving on to step 2:
142 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 142

Going ahead to step 3:
690 divided by 142 is 4 with a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 568 away from 690, we end up with 122.
Include the next digit (8) from the dividend after 122, then repeat: 1228 / 142

On to step 4:
When dividing 1228 by 142, we get 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 1136 away from 1228, we end up with 92.
Take the next digit (6) from the dividend and append it to 92, then repeat: 926 / 142

Moving on to step 5:
926 divided by 142 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 486.0
Subtracting 852 from 926 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 142

Let's proceed to step 6:
142 goes into 749 5 times with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 4865.0
Subtracting 710 from 749 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 142

Step 7:
142 goes into 390 2 times with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 48652.0
If we subtract 284 from 390, we get 106.
Grab the next digit (4) from the dividend, add it to 106, then carry on: 1064 / 142

Advancing to step 8:
The number 142 fits into 1064 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 486527.0
The remainder is 70 after subtracting 994 from 1064.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
142 can be fit into 700 4 times, resulting in a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 486527.4
If we subtract 568 from 700, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
142 can be fit into 1320 9 times, resulting in a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 486527.49
The remainder is 42 after subtracting 1278 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
The number 142 fits into 420 2 times, leaving a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 486527.492
Subtract 284 from 420 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
1360 divided by 142 is 9 with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 486527.4929
If we take 1278 away from 1360, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 13:
142 can be fit into 820 5 times, resulting in a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 486527.49295
Subtracting 710 from 820 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
The number 142 fits into 1100 7 times, leaving a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 486527.492957
Subtracting 994 from 1100 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 15:
142 can be fit into 1060 7 times, resulting in a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 486527.4929577
Deduct 994 from 1060 and we're left 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.

After the division, we end up with 486527.4929577 and a remainder of 6.6e-07.
