Let's divide 40191660 by 590
Let's see how many times 590 fits into 40191660.

On to step 1:
When dividing 4 by 590, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 590

Advancing to step 2:
When dividing 40 by 590, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 590

On to step 3:
590 goes into 401 0 times with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Grab the next digit (9) from the dividend, add it to 401, then carry on: 4019 / 590

Going ahead to step 4:
If we divide 4019 by 590, we get 6 and a remainder of 479.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3540 from 4019 and we're left with 479.
Grab the next digit (1) from the dividend, add it to 479, then carry on: 4791 / 590

Advancing to step 5:
The number 590 fits into 4791 8 times, leaving a remainder of 71.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 4720 from 4791 leaves us with 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 590

On to step 6:
590 can be fit into 716 1 times, resulting in a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 681.0
The remainder is 126 after subtracting 590 from 716.
Grab the next digit (6) from the dividend, add it to 126, then carry on: 1266 / 590

Moving on to step 7:
590 can be fit into 1266 2 times, resulting in a remainder of 86.
The next digit of our result is 2. 
Result so far: 6812.0
Deduct 1180 from 1266 and we're left with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 590

Advancing to step 8:
The number 590 fits into 860 1 times, leaving a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 68121.0
If we subtract 590 from 860, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 9:
The number 590 fits into 2700 4 times, leaving a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 68121.4
If we take 2360 away from 2700, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
590 goes into 3400 5 times with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 68121.45
If we take 2950 away from 3400, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 11:
590 can be fit into 4500 7 times, resulting in a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 68121.457
If we subtract 4130 from 4500, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 12:
590 goes into 3700 6 times with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 68121.4576
If we take 3540 away from 3700, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
If we divide 1600 by 590, we get 2 and a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 68121.45762
The remainder is 420 after subtracting 1180 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
590 goes into 4200 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 68121.457627
Subtracting 4130 from 4200 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 15:
The number 590 fits into 700 1 times, leaving a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 68121.4576271
Subtracting 590 from 700 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
590 can be fit into 1100 1 times, resulting in a remainder of 510.
The next digit of our result is 1. 
Result so far: 68121.45762711
The remainder is 510 after subtracting 590 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The final result is 68121.45762711 with a remainder of 5.1e-07.
