43695180 ÷ 840 
We want to figure out the number of times 43695180 can be divided by 840.

Advancing to step 1:
840 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 840

Moving on to step 2:
840 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 840

Moving on to step 3:
The number 840 fits into 436 0 times, leaving a remainder of 436.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Include the next digit (9) from the dividend after 436, then repeat: 4369 / 840

Advancing to step 4:
When dividing 4369 by 840, we get 5 with a remainder of 169.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 169 after subtracting 4200 from 4369.
Include the next digit (5) from the dividend after 169, then repeat: 1695 / 840

Moving on to step 5:
When dividing 1695 by 840, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 52.0
If we take 1680 away from 1695, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 840

Moving on to step 6:
If we divide 151 by 840, we get 0 and a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 520.0
The remainder is 151 after subtracting 0 from 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 840

Let's proceed to step 7:
840 can be fit into 1518 1 times, resulting in a remainder of 678.
Use 1 as the next digit of our solution. 
Result so far: 5201.0
If we take 840 away from 1518, we end up with 678.
Append the next digit (0) from the dividend to 678 and continue with: 6780 / 840

Let's proceed to step 8:
840 goes into 6780 8 times with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 52018.0
The remainder is 60 after subtracting 6720 from 6780.
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:
If we divide 600 by 840, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 52018.0
Subtract 0 from 600 to 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.

Moving on to step 10:
If we divide 6000 by 840, we get 7 and a remainder of 120.
The next digit of our result is 7. 
Result so far: 52018.07
Subtracting 5880 from 6000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
If we divide 1200 by 840, we get 1 and a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 52018.071
Subtracting 840 from 1200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 52018.0714
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
840 goes into 2400 2 times with a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 52018.07142
Subtracting 1680 from 2400 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 14:
840 goes into 7200 8 times with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 52018.071428
Subtract 6720 from 7200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 15:
840 goes into 4800 5 times with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 52018.0714285
If we take 4200 away from 4800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 16:
6000 divided by 840 is 7 with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 52018.07142857
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 52018.07142857 and a remainder of 1.2e-07.
