We're dividing 52909142 by 142 
We want to figure out the number of times 52909142 can be divided by 142.

Moving on to step 1:
142 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 142

Advancing to step 2:
142 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 142

Let's proceed to step 3:
If we divide 529 by 142, we get 3 and a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 426 away from 529, we end up with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 142

On to step 4:
1030 divided by 142 is 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 994 from 1030 leaves us with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 142

Advancing to step 5:
369 divided by 142 is 2 with a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
Subtract 284 from 369 to get 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 142

Advancing to step 6:
When dividing 851 by 142, we get 5 with a remainder of 141.
Write down 5 as next digit of the result. 
Result so far: 3725.0
The remainder is 141 after subtracting 710 from 851.
Fetch the next digit (4) from the dividend, attach it to 141 and continue: 1414 / 142

Moving on to step 7:
1414 divided by 142 is 9 with a remainder of 136.
Use 9 as the next digit of our solution. 
Result so far: 37259.0
Deduct 1278 from 1414 and we're left with 136.
Grab the next digit (2) from the dividend, add it to 136, then carry on: 1362 / 142

Step 8:
When dividing 1362 by 142, we get 9 with a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 372599.0
If we subtract 1278 from 1362, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
The number 142 fits into 840 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 372599.5
If we take 710 away from 840, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
1300 divided by 142 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 372599.59
If we subtract 1278 from 1300, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
If we divide 220 by 142, we get 1 and a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 372599.591
Subtract 142 from 220 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
780 divided by 142 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 372599.5915
If we subtract 710 from 780, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
142 can be fit into 700 4 times, resulting in a remainder of 132.
The next digit of our result is 4. 
Result so far: 372599.59154
If we take 568 away from 700, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
If we divide 1320 by 142, we get 9 and a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 372599.591549
If we subtract 1278 from 1320, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
If we divide 420 by 142, we get 2 and a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 372599.5915492
Deduct 284 from 420 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
142 can be fit into 1360 9 times, resulting in a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 372599.59154929
Subtracting 1278 from 1360 leaves us 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.

The final result is 372599.59154929 with a remainder of 8.2e-08.
