We're dividing 42347246 by 991 
Let's see how many times 991 fits into 42347246.

Let's proceed to step 1:
If we divide 4 by 991, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 991

Moving on to step 2:
The number 991 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 991

Moving on to step 3:
991 goes into 423 0 times with a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Take the next digit (4) from the dividend and append it to 423, then repeat: 4234 / 991

Let's proceed to step 4:
991 can be fit into 4234 4 times, resulting in a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3964 from 4234, we get 270.
Bring next digit (7) of the dividend behind the 270 and repeat the process: 2707 / 991

Going ahead to step 5:
If we divide 2707 by 991, we get 2 and a remainder of 725.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 1982 from 2707, we get 725.
Append the next digit (2) from the dividend to 725 and continue with: 7252 / 991

Advancing to step 6:
If we divide 7252 by 991, we get 7 and a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtract 6937 from 7252 to get 315.
Grab the next digit (4) from the dividend, add it to 315, then carry on: 3154 / 991

On to step 7:
991 goes into 3154 3 times with a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 4273.0
The remainder is 181 after subtracting 2973 from 3154.
Take the next digit (6) from the dividend and append it to 181, then repeat: 1816 / 991

Moving on to step 8:
If we divide 1816 by 991, we get 1 and a remainder of 825.
The next digit of our result is 1. 
Result so far: 42731.0
The remainder is 825 after subtracting 991 from 1816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

On to step 9:
991 can be fit into 8250 8 times, resulting in a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 42731.8
The remainder is 322 after subtracting 7928 from 8250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
The number 991 fits into 3220 3 times, leaving a remainder of 247.
The next digit of our result is 3. 
Result so far: 42731.83
If we take 2973 away from 3220, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 11:
991 goes into 2470 2 times with a remainder of 488.
Put 2 as the next digit of the answer. 
Result so far: 42731.832
If we take 1982 away from 2470, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 12:
4880 divided by 991 is 4 with a remainder of 916.
Put 4 as the next digit of the answer. 
Result so far: 42731.8324
If we take 3964 away from 4880, we end up with 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

Advancing to step 13:
991 goes into 9160 9 times with a remainder of 241.
The next digit of our result is 9. 
Result so far: 42731.83249
Deduct 8919 from 9160 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 14:
991 goes into 2410 2 times with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 42731.832492
Subtract 1982 from 2410 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 15:
991 can be fit into 4280 4 times, resulting in a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 42731.8324924
The remainder is 316 after subtracting 3964 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 16:
3160 divided by 991 is 3 with a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 42731.83249243
Deduct 2973 from 3160 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

In conclusion, the division gives 42731.83249243 with a balance of 1.87e-07.
