43688913 ÷ 671 
We want to figure out the number of times 43688913 can be divided by 671.

Let's proceed to step 1:
671 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 671

Step 2:
43 divided by 671 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 671

Going ahead to step 3:
The number 671 fits into 436 0 times, leaving a remainder of 436.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 436 to get 436.
Bring next digit (8) of the dividend behind the 436 and repeat the process: 4368 / 671

Let's proceed to step 4:
If we divide 4368 by 671, we get 6 and a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4026 from 4368 to get 342.
Take the next digit (8) from the dividend and append it to 342, then repeat: 3428 / 671

Advancing to step 5:
671 can be fit into 3428 5 times, resulting in a remainder of 73.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 3355 from 3428 and we're left with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 671

Let's proceed to step 6:
If we divide 739 by 671, we get 1 and a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
If we subtract 671 from 739, we get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 671

Step 7:
681 divided by 671 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6511.0
If we subtract 671 from 681, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 671

Step 8:
103 divided by 671 is 0 with a remainder of 103.
Record the quotient 0 as the next digit in the result. 
Result so far: 65110.0
Subtracting 0 from 103 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 9:
When dividing 1030 by 671, we get 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 65110.1
If we subtract 671 from 1030, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 10:
671 goes into 3590 5 times with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 65110.15
Deduct 3355 from 3590 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 11:
If we divide 2350 by 671, we get 3 and a remainder of 337.
The number 3 becomes the next digit in our result. 
Result so far: 65110.153
If we subtract 2013 from 2350, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 12:
671 can be fit into 3370 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 65110.1535
If we take 3355 away from 3370, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
When dividing 150 by 671, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 65110.1535
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
1500 divided by 671 is 2 with a remainder of 158.
The next digit of our result is 2. 
Result so far: 65110.153502
Subtracting 1342 from 1500 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 15:
671 can be fit into 1580 2 times, resulting in a remainder of 238.
The next digit of our result is 2. 
Result so far: 65110.1535022
Deduct 1342 from 1580 and we're left 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.

The final result is 65110.1535022 with a remainder of 2.38e-06.
