We look at the division of 43991045 by 658 
We want to figure out the number of times 43991045 can be divided by 658.

Step 1:
The number 658 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 658

Advancing to step 2:
658 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 658

Moving on to step 3:
When dividing 439 by 658, we get 0 with a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 439 to get 439.
Bring next digit (9) of the dividend behind the 439 and repeat the process: 4399 / 658

Let's proceed to step 4:
When dividing 4399 by 658, we get 6 with a remainder of 451.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 451 after subtracting 3948 from 4399.
Bring next digit (1) of the dividend behind the 451 and repeat the process: 4511 / 658

Going ahead to step 5:
The number 658 fits into 4511 6 times, leaving a remainder of 563.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 3948 away from 4511, we end up with 563.
Bring next digit (0) of the dividend behind the 563 and repeat the process: 5630 / 658

Moving on to step 6:
When dividing 5630 by 658, we get 8 with a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
If we subtract 5264 from 5630, we get 366.
Grab the next digit (4) from the dividend, add it to 366, then carry on: 3664 / 658

Let's proceed to step 7:
When dividing 3664 by 658, we get 5 with a remainder of 374.
Use 5 as the next digit of our solution. 
Result so far: 6685.0
The remainder is 374 after subtracting 3290 from 3664.
Append the next digit (5) from the dividend to 374 and continue with: 3745 / 658

Step 8:
If we divide 3745 by 658, we get 5 and a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 66855.0
Subtract 3290 from 3745 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 9:
If we divide 4550 by 658, we get 6 and a remainder of 602.
Put 6 as the next digit of the answer. 
Result so far: 66855.6
If we take 3948 away from 4550, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

On to step 10:
If we divide 6020 by 658, we get 9 and a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 66855.69
If we take 5922 away from 6020, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 11:
The number 658 fits into 980 1 times, leaving a remainder of 322.
The next digit of our result is 1. 
Result so far: 66855.691
Subtract 658 from 980 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 12:
3220 divided by 658 is 4 with a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 66855.6914
Subtracting 2632 from 3220 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 13:
5880 divided by 658 is 8 with a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 66855.69148
If we subtract 5264 from 5880, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 14:
658 can be fit into 6160 9 times, resulting in a remainder of 238.
The number 9 becomes the next digit in our result. 
Result so far: 66855.691489
Subtracting 5922 from 6160 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 15:
658 can be fit into 2380 3 times, resulting in a remainder of 406.
The next digit of our result is 3. 
Result so far: 66855.6914893
The remainder is 406 after subtracting 1974 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 16:
4060 divided by 658 is 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 66855.69148936
If we subtract 3948 from 4060, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 66855.69148936, and the remainder is 1.12e-07.
