43786836 ÷ 685 
We want to divide 43786836 by 685.

On to step 1:
4 divided by 685 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 685

Let's proceed to step 2:
685 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 685

Advancing to step 3:
When dividing 437 by 685, we get 0 with a remainder of 437.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 437 after subtracting 0 from 437.
Include the next digit (8) from the dividend after 437, then repeat: 4378 / 685

Let's proceed to step 4:
The number 685 fits into 4378 6 times, leaving a remainder of 268.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 4110 from 4378 to get 268.
Include the next digit (6) from the dividend after 268, then repeat: 2686 / 685

Advancing to step 5:
If we divide 2686 by 685, we get 3 and a remainder of 631.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 2055 away from 2686, we end up with 631.
Grab the next digit (8) from the dividend, add it to 631, then carry on: 6318 / 685

Let's proceed to step 6:
685 goes into 6318 9 times with a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 639.0
Subtract 6165 from 6318 to get 153.
Grab the next digit (3) from the dividend, add it to 153, then carry on: 1533 / 685

On to step 7:
1533 divided by 685 is 2 with a remainder of 163.
Record the quotient 2 as the next digit in the result. 
Result so far: 6392.0
Deduct 1370 from 1533 and we're left with 163.
Grab the next digit (6) from the dividend, add it to 163, then carry on: 1636 / 685

Moving on to step 8:
685 can be fit into 1636 2 times, resulting in a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 63922.0
If we take 1370 away from 1636, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 9:
The number 685 fits into 2660 3 times, leaving a remainder of 605.
Record the quotient 3 as the next digit in the result. 
Result so far: 63922.3
Subtract 2055 from 2660 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 10:
If we divide 6050 by 685, we get 8 and a remainder of 570.
Record the quotient 8 as the next digit in the result. 
Result so far: 63922.38
If we subtract 5480 from 6050, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 11:
685 can be fit into 5700 8 times, resulting in a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 63922.388
Deduct 5480 from 5700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 63922.388 with a remainder of 0.022.
