43603394 divided by 142 
We're looking to find how many times 142 goes into 43603394.

Going ahead to step 1:
The number 142 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 142

On to step 2:
142 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 142

Advancing to step 3:
If we divide 436 by 142, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 426 away from 436, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 142

Step 4:
142 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 100, we get 100.
Take the next digit (3) from the dividend and append it to 100, then repeat: 1003 / 142

Moving on to step 5:
142 can be fit into 1003 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 307.0
The remainder is 9 after subtracting 994 from 1003.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 142

Moving on to step 6:
When dividing 93 by 142, we get 0 with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 3070.0
Subtract 0 from 93 to get 93.
Bring next digit (9) of the dividend behind the 93 and repeat the process: 939 / 142

Let's proceed to step 7:
When dividing 939 by 142, we get 6 with a remainder of 87.
The next digit of our result is 6. 
Result so far: 30706.0
If we take 852 away from 939, we end up with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 142

Moving on to step 8:
874 divided by 142 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 307066.0
If we take 852 away from 874, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 142, we get 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 307066.1
Subtracting 142 from 220 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
142 can be fit into 780 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 307066.15
Deduct 710 from 780 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
142 can be fit into 700 4 times, resulting in a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 307066.154
Subtracting 568 from 700 leaves us 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.

Let's proceed to step 12:
1320 divided by 142 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 307066.1549
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.

Let's proceed to step 13:
142 can be fit into 420 2 times, resulting in a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 307066.15492
Subtracting 284 from 420 leaves us 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.

Advancing to step 14:
If we divide 1360 by 142, we get 9 and a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 307066.154929
Deduct 1278 from 1360 and we're left 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.

Let's proceed to step 15:
142 goes into 820 5 times with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 307066.1549295
If we subtract 710 from 820, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
The number 142 fits into 1100 7 times, leaving a remainder of 106.
The next digit of our result is 7. 
Result so far: 307066.15492957
Subtract 994 from 1100 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 307066.15492957 and a remainder of 1.06e-07.
