We look at the division of 40570230 by 551 
We want to figure out the number of times 40570230 can be divided by 551.

Step 1:
The number 551 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 551

Let's proceed to step 2:
When dividing 40 by 551, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 551

Let's proceed to step 3:
If we divide 405 by 551, we get 0 and a remainder of 405.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 405 after subtracting 0 from 405.
Append the next digit (7) from the dividend to 405 and continue with: 4057 / 551

Step 4:
551 can be fit into 4057 7 times, resulting in a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 3857 away from 4057, we end up with 200.
Grab the next digit (0) from the dividend, add it to 200, then carry on: 2000 / 551

Moving on to step 5:
551 can be fit into 2000 3 times, resulting in a remainder of 347.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 1653 from 2000, we get 347.
Grab the next digit (2) from the dividend, add it to 347, then carry on: 3472 / 551

Step 6:
551 can be fit into 3472 6 times, resulting in a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 736.0
Subtract 3306 from 3472 to get 166.
Include the next digit (3) from the dividend after 166, then repeat: 1663 / 551

On to step 7:
If we divide 1663 by 551, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 7363.0
If we subtract 1653 from 1663, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 551

Step 8:
551 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 73630.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
The number 551 fits into 1000 1 times, leaving a remainder of 449.
The next digit of our result is 1. 
Result so far: 73630.1
The remainder is 449 after subtracting 551 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 10:
When dividing 4490 by 551, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 73630.18
The remainder is 82 after subtracting 4408 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
551 can be fit into 820 1 times, resulting in a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 73630.181
Deduct 551 from 820 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 12:
2690 divided by 551 is 4 with a remainder of 486.
Write down 4 as next digit of the result. 
Result so far: 73630.1814
Subtract 2204 from 2690 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 13:
551 can be fit into 4860 8 times, resulting in a remainder of 452.
Use 8 as the next digit of our solution. 
Result so far: 73630.18148
Subtract 4408 from 4860 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 14:
When dividing 4520 by 551, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 73630.181488
Subtracting 4408 from 4520 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 73630.181488, and the remainder is 1.12e-05.
