We're dividing 43437099 by 213 
We want to divide 43437099 by 213.

Advancing to step 1:
213 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
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 / 213

Step 2:
The number 213 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 213

Moving on to step 3:
213 goes into 434 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 426 from 434 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 213

Going ahead to step 4:
83 divided by 213 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 213

Step 5:
213 can be fit into 837 3 times, resulting in a remainder of 198.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Subtracting 639 from 837 leaves us with 198.
Fetch the next digit (0) from the dividend, attach it to 198 and continue: 1980 / 213

Advancing to step 6:
213 can be fit into 1980 9 times, resulting in a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 2039.0
Subtract 1917 from 1980 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 213

Moving on to step 7:
When dividing 639 by 213, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 20393.0
If we take 639 away from 639, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 213

Moving on to step 8:
The number 213 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 203930.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
213 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 203930.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 213 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 203930.04
Subtracting 852 from 900 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
213 can be fit into 480 2 times, resulting in a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 203930.042
Subtracting 426 from 480 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
213 can be fit into 540 2 times, resulting in a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 203930.0422
If we take 426 away from 540, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 203930.0422, and the remainder is 0.00114.
