43342473 ÷ 166 
Our goal is to divide 43342473 by 166.

Going ahead to step 1:
166 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 166

Moving on to step 2:
43 divided by 166 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 166

Advancing to step 3:
166 goes into 433 2 times with a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 332 from 433 to get 101.
Take the next digit (4) from the dividend and append it to 101, then repeat: 1014 / 166

On to step 4:
1014 divided by 166 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 996 from 1014 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 166

Going ahead to step 5:
If we divide 182 by 166, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Subtracting 166 from 182 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 166

Step 6:
The number 166 fits into 164 0 times, leaving a remainder of 164.
The next digit of our result is 0. 
Result so far: 2610.0
The remainder is 164 after subtracting 0 from 164.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 166

On to step 7:
If we divide 1647 by 166, we get 9 and a remainder of 153.
Record the quotient 9 as the next digit in the result. 
Result so far: 26109.0
The remainder is 153 after subtracting 1494 from 1647.
Grab the next digit (3) from the dividend, add it to 153, then carry on: 1533 / 166

Step 8:
166 can be fit into 1533 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 261099.0
Subtracting 1494 from 1533 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
390 divided by 166 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 261099.2
The remainder is 58 after subtracting 332 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
166 can be fit into 580 3 times, resulting in a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 261099.23
If we take 498 away from 580, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
166 can be fit into 820 4 times, resulting in a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 261099.234
If we take 664 away from 820, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 12:
1560 divided by 166 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 261099.2349
If we take 1494 away from 1560, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
When dividing 660 by 166, we get 3 with a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 261099.23493
Deduct 498 from 660 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 14:
The number 166 fits into 1620 9 times, leaving a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 261099.234939
Deduct 1494 from 1620 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 15:
1260 divided by 166 is 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 261099.2349397
Deduct 1162 from 1260 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
The number 166 fits into 980 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 261099.23493975
Deduct 830 from 980 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 261099.23493975, and the remainder is 1.5e-07.
