Let's divide 43124937 by 991
We want to divide 43124937 by 991.

Step 1:
991 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 991

Advancing to step 2:
991 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 991

Step 3:
The number 991 fits into 431 0 times, leaving a remainder of 431.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 431 after subtracting 0 from 431.
Bring next digit (2) of the dividend behind the 431 and repeat the process: 4312 / 991

On to step 4:
991 can be fit into 4312 4 times, resulting in a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3964 away from 4312, we end up with 348.
Bring next digit (4) of the dividend behind the 348 and repeat the process: 3484 / 991

Moving on to step 5:
991 can be fit into 3484 3 times, resulting in a remainder of 511.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 2973 from 3484 and we're left with 511.
Include the next digit (9) from the dividend after 511, then repeat: 5119 / 991

Let's proceed to step 6:
When dividing 5119 by 991, we get 5 with a remainder of 164.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
If we subtract 4955 from 5119, we get 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 991

Advancing to step 7:
If we divide 1643 by 991, we get 1 and a remainder of 652.
Write down 1 as next digit of the result. 
Result so far: 4351.0
Subtract 991 from 1643 to get 652.
Fetch the next digit (7) from the dividend, attach it to 652 and continue: 6527 / 991

Going ahead to step 8:
991 can be fit into 6527 6 times, resulting in a remainder of 581.
Use 6 as the next digit of our solution. 
Result so far: 43516.0
Subtract 5946 from 6527 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 9:
5810 divided by 991 is 5 with a remainder of 855.
The number 5 becomes the next digit in our result. 
Result so far: 43516.5
Subtracting 4955 from 5810 leaves us with 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

Moving on to step 10:
If we divide 8550 by 991, we get 8 and a remainder of 622.
Use 8 as the next digit of our solution. 
Result so far: 43516.58
Deduct 7928 from 8550 and we're left with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 11:
When dividing 6220 by 991, we get 6 with a remainder of 274.
Write down 6 as next digit of the result. 
Result so far: 43516.586
If we take 5946 away from 6220, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 12:
When dividing 2740 by 991, we get 2 with a remainder of 758.
Use 2 as the next digit of our solution. 
Result so far: 43516.5862
If we take 1982 away from 2740, we end up with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Let's proceed to step 13:
When dividing 7580 by 991, we get 7 with a remainder of 643.
Record the quotient 7 as the next digit in the result. 
Result so far: 43516.58627
If we take 6937 away from 7580, we end up with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Moving on to step 14:
The number 991 fits into 6430 6 times, leaving a remainder of 484.
Put 6 as the next digit of the answer. 
Result so far: 43516.586276
Deduct 5946 from 6430 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 15:
991 goes into 4840 4 times with a remainder of 876.
Use 4 as the next digit of our solution. 
Result so far: 43516.5862764
If we subtract 3964 from 4840, we get 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

On to step 16:
If we divide 8760 by 991, we get 8 and a remainder of 832.
The next digit of our result is 8. 
Result so far: 43516.58627648
If we subtract 7928 from 8760, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

The final result is 43516.58627648 with a remainder of 8.32e-07.
