97401209 ÷ 142 
Let's see how many times 142 fits into 97401209.

Step 1:
142 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 142

Step 2:
If we divide 97 by 142, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 142

Going ahead to step 3:
142 goes into 974 6 times with a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 852 from 974 leaves us with 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 142

Advancing to step 4:
If we divide 1220 by 142, we get 8 and a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 1136 from 1220, we get 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 142

On to step 5:
142 goes into 841 5 times with a remainder of 131.
The next digit of our result is 5. 
Result so far: 685.0
Subtract 710 from 841 to get 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 142

Step 6:
The number 142 fits into 1312 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 6859.0
Subtracting 1278 from 1312 leaves us with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 142

Going ahead to step 7:
If we divide 340 by 142, we get 2 and a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 68592.0
If we take 284 away from 340, we end up with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 142

Going ahead to step 8:
If we divide 569 by 142, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 685924.0
Subtracting 568 from 569 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
142 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 685924.0
If we subtract 0 from 10, we 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.

Step 10:
When dividing 100 by 142, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 685924.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 685924.0 with a remainder of 0.1.
