45197588 divided by 991 
We want to figure out the number of times 45197588 can be divided 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
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 991

Step 2:
The number 991 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 991

Moving on to step 3:
When dividing 451 by 991, we get 0 with a remainder of 451.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 451 after subtracting 0 from 451.
Fetch the next digit (9) from the dividend, attach it to 451 and continue: 4519 / 991

Let's proceed to step 4:
If we divide 4519 by 991, we get 4 and a remainder of 555.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3964 from 4519 and we're left with 555.
Bring next digit (7) of the dividend behind the 555 and repeat the process: 5557 / 991

Advancing to step 5:
991 goes into 5557 5 times with a remainder of 602.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 4955 from 5557 leaves us with 602.
Append the next digit (5) from the dividend to 602 and continue with: 6025 / 991

On to step 6:
If we divide 6025 by 991, we get 6 and a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
The remainder is 79 after subtracting 5946 from 6025.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 991

Moving on to step 7:
The number 991 fits into 798 0 times, leaving a remainder of 798.
Put 0 as the next digit of the answer. 
Result so far: 4560.0
If we take 0 away from 798, we end up with 798.
Append the next digit (8) from the dividend to 798 and continue with: 7988 / 991

Step 8:
When dividing 7988 by 991, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 45608.0
If we subtract 7928 from 7988, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 991 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 45608.0
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
If we divide 6000 by 991, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 45608.06
Subtract 5946 from 6000 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
991 goes into 540 0 times with a remainder of 540.
The next digit of our result is 0. 
Result so far: 45608.06
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
When dividing 5400 by 991, we get 5 with a remainder of 445.
The next digit of our result is 5. 
Result so far: 45608.0605
Subtracting 4955 from 5400 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 13:
When dividing 4450 by 991, we get 4 with a remainder of 486.
The number 4 becomes the next digit in our result. 
Result so far: 45608.06054
Deduct 3964 from 4450 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 14:
When dividing 4860 by 991, we get 4 with a remainder of 896.
Write down 4 as next digit of the result. 
Result so far: 45608.060544
Subtract 3964 from 4860 to get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

The final result is 45608.060544 with a remainder of 8.96e-05.
