We're dividing 601990 by 43 
We want to figure out the number of times 601990 can be divided by 43.

Let's proceed to step 1:
6 divided by 43 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 43

Moving on to step 2:
43 can be fit into 60 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 43 from 60 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 43

Advancing to step 3:
171 divided by 43 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 129 from 171, we get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 43

Moving on to step 4:
The number 43 fits into 429 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 139.0
The remainder is 42 after subtracting 387 from 429.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 43

Step 5:
When dividing 429 by 43, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 1399.0
If we subtract 387 from 429, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 43

On to step 6:
If we divide 420 by 43, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 13999.0
Deduct 387 from 420 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 13999.7
Subtracting 301 from 330 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
If we divide 290 by 43, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 13999.76
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
43 goes into 320 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 13999.767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 13999.7674
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 43 fits into 180 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13999.76744
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 13999.76744, with a leftover of 8e-06.
