151381 ÷ 43 
We want to figure out the number of times 151381 can be divided by 43.

Moving on to step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 43

Step 2:
When dividing 15 by 43, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 43

Advancing to step 3:
43 can be fit into 151 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 22 after subtracting 129 from 151.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 43

Moving on to step 4:
When dividing 223 by 43, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 215 from 223, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 43

Going ahead to step 5:
If we divide 88 by 43, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 352.0
Subtract 86 from 88 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 43

Going ahead to step 6:
If we divide 21 by 43, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 3520.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
43 goes into 210 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 3520.4
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 43, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 3520.48
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 43 fits into 360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 3520.488
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 3520.488 and a remainder of 0.0016.
