43408035 divided by 142 
Our goal is to divide 43408035 by 142.

Step 1:
When dividing 4 by 142, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 142

On to step 2:
142 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 142

Let's proceed to step 3:
142 can be fit into 434 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 426 from 434 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 142

Going ahead to step 4:
80 divided by 142 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 80, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 142

Advancing to step 5:
142 goes into 808 5 times with a remainder of 98.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
If we take 710 away from 808, we end up with 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 142

Moving on to step 6:
When dividing 980 by 142, we get 6 with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 3056.0
Subtract 852 from 980 to get 128.
Bring next digit (3) of the dividend behind the 128 and repeat the process: 1283 / 142

Moving on to step 7:
If we divide 1283 by 142, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 30569.0
The remainder is 5 after subtracting 1278 from 1283.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 142

Going ahead to step 8:
If we divide 55 by 142, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 305690.0
The remainder is 55 after subtracting 0 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
The number 142 fits into 550 3 times, leaving a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 305690.3
Subtract 426 from 550 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
When dividing 1240 by 142, we get 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 305690.38
If we take 1136 away from 1240, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
When dividing 1040 by 142, we get 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 305690.387
Subtracting 994 from 1040 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
142 goes into 460 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 305690.3873
Subtracting 426 from 460 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
When dividing 340 by 142, we get 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 305690.38732
If we subtract 284 from 340, we 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.

Step 14:
560 divided by 142 is 3 with a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 305690.387323
If we take 426 away from 560, we end up 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 15:
1340 divided by 142 is 9 with a remainder of 62.
The next digit of our result is 9. 
Result so far: 305690.3873239
If we take 1278 away from 1340, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 16:
142 goes into 620 4 times with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 305690.38732394
If we subtract 568 from 620, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 305690.38732394 with a remainder of 5.2e-08.
