40390591 ÷ 601 
We want to divide 40390591 by 601.

Going ahead to step 1:
601 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 601

Going ahead to step 2:
40 divided by 601 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 601

Let's proceed to step 3:
When dividing 403 by 601, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 403 after subtracting 0 from 403.
Append the next digit (9) from the dividend to 403 and continue with: 4039 / 601

Step 4:
601 can be fit into 4039 6 times, resulting in a remainder of 433.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3606 from 4039 leaves us with 433.
Take the next digit (0) from the dividend and append it to 433, then repeat: 4330 / 601

Moving on to step 5:
601 can be fit into 4330 7 times, resulting in a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 4207 from 4330 to get 123.
Fetch the next digit (5) from the dividend, attach it to 123 and continue: 1235 / 601

Moving on to step 6:
When dividing 1235 by 601, we get 2 with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 672.0
The remainder is 33 after subtracting 1202 from 1235.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 601

Let's proceed to step 7:
601 can be fit into 339 0 times, resulting in a remainder of 339.
Record the quotient 0 as the next digit in the result. 
Result so far: 6720.0
If we subtract 0 from 339, we get 339.
Bring next digit (1) of the dividend behind the 339 and repeat the process: 3391 / 601

On to step 8:
601 can be fit into 3391 5 times, resulting in a remainder of 386.
The next digit of our result is 5. 
Result so far: 67205.0
If we take 3005 away from 3391, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 9:
If we divide 3860 by 601, we get 6 and a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 67205.6
Deduct 3606 from 3860 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 10:
601 goes into 2540 4 times with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 67205.64
Deduct 2404 from 2540 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
601 can be fit into 1360 2 times, resulting in a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 67205.642
If we subtract 1202 from 1360, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 12:
1580 divided by 601 is 2 with a remainder of 378.
The number 2 becomes the next digit in our result. 
Result so far: 67205.6422
Subtracting 1202 from 1580 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 67205.6422, with a leftover of 0.00378.
