237639 divided by 43 
We're looking to find how many times 43 goes into 237639.

Going ahead to step 1:
2 divided by 43 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 43

Step 2:
The number 43 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 43

Step 3:
When dividing 237 by 43, we get 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 215 from 237 to get 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 43

Advancing to step 4:
226 divided by 43 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 11 after subtracting 215 from 226.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 43

Moving on to step 5:
43 goes into 113 2 times with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 552.0
Subtracting 86 from 113 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 43

Advancing to step 6:
When dividing 279 by 43, we get 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 5526.0
Deduct 258 from 279 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 5526.4
Subtract 172 from 210 to get 38.
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:
43 goes into 380 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 5526.48
Subtract 344 from 380 to 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.

Moving on to step 9:
43 goes into 360 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 5526.488
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 5526.488, with a leftover of 0.0016.
