43698057 divided by 12 
We want to figure out the number of times 43698057 can be divided by 12.

Let's proceed to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 12

Advancing to step 2:
43 divided by 12 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 36 from 43 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 12

Advancing to step 3:
When dividing 76 by 12, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 72 away from 76, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 12

Advancing to step 4:
The number 12 fits into 49 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 364.0
Subtract 48 from 49 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 12

Step 5:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 3641.0
Subtract 12 from 18 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 12

Step 6:
12 goes into 60 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 36415.0
Subtract 60 from 60 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

Step 7:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 364150.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Going ahead to step 8:
57 divided by 12 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 3641504.0
The remainder is 9 after subtracting 48 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 12, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3641504.7
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
12 goes into 60 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3641504.75
If we take 60 away from 60, we end up 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.

Step 11:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3641504.75
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.

Step 12:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3641504.75
If we subtract 0 from 0, 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.

The quotient of the division is 3641504.75, and the remainder is 0.0.
