43659978 ÷ 10 
We want to divide 43659978 by 10.

Moving on to step 1:
If we divide 4 by 10, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 10

Advancing to step 2:
43 divided by 10 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 40 away from 43, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 10

On to step 3:
10 can be fit into 36 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 30 from 36, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 10

Going ahead to step 4:
When dividing 65 by 10, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Subtract 60 from 65 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 10

Advancing to step 5:
The number 10 fits into 59 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 4365.0
If we take 50 away from 59, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 10

Step 6:
If we divide 99 by 10, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 43659.0
Subtract 90 from 99 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 10

Step 7:
When dividing 97 by 10, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 436599.0
Subtracting 90 from 97 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 10

Advancing to step 8:
10 goes into 78 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 4365997.0
Subtracting 70 from 78 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 10, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4365997.8
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4365997.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4365997.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4365997.8, and the remainder is 0.0.
