61793109 ÷ 142 
We want to figure out the number of times 61793109 can be divided by 142.

Advancing to step 1:
The number 142 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 142

Going ahead to step 2:
When dividing 61 by 142, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 142

Moving on to step 3:
142 goes into 617 4 times with a remainder of 49.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 49 after subtracting 568 from 617.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 142

Moving on to step 4:
When dividing 499 by 142, we get 3 with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 426 from 499 leaves us with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 142

Going ahead to step 5:
If we divide 733 by 142, we get 5 and a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
Subtract 710 from 733 to get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 142

Let's proceed to step 6:
When dividing 231 by 142, we get 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 4351.0
If we take 142 away from 231, we end up with 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 142

Advancing to step 7:
142 can be fit into 890 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 43516.0
If we take 852 away from 890, we end up with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 142

On to step 8:
389 divided by 142 is 2 with a remainder of 105.
The next digit of our result is 2. 
Result so far: 435162.0
Deduct 284 from 389 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 9:
If we divide 1050 by 142, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 435162.7
Subtract 994 from 1050 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 142 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 435162.73
Deduct 426 from 560 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 11:
If we divide 1340 by 142, we get 9 and a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 435162.739
Subtract 1278 from 1340 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 12:
When dividing 620 by 142, we get 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 435162.7394
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
142 goes into 520 3 times with a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 435162.73943
The remainder is 94 after subtracting 426 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 14:
The number 142 fits into 940 6 times, leaving a remainder of 88.
The next digit of our result is 6. 
Result so far: 435162.739436
If we take 852 away from 940, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
880 divided by 142 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 435162.7394366
If we take 852 away from 880, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 435162.7394366 and a remainder of 2.8e-07.
