40278895 ÷ 210 
We're looking to find how many times 210 goes into 40278895.

Moving on to step 1:
210 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 210

Let's proceed to step 2:
210 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 210

Going ahead to step 3:
210 can be fit into 402 1 times, resulting in a remainder of 192.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 210 from 402, we get 192.
Take the next digit (7) from the dividend and append it to 192, then repeat: 1927 / 210

Let's proceed to step 4:
If we divide 1927 by 210, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 1890 from 1927 leaves us with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 210

On to step 5:
The number 210 fits into 378 1 times, leaving a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
The remainder is 168 after subtracting 210 from 378.
Include the next digit (8) from the dividend after 168, then repeat: 1688 / 210

Step 6:
The number 210 fits into 1688 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1918.0
If we subtract 1680 from 1688, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 210

Moving on to step 7:
If we divide 89 by 210, we get 0 and a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 19180.0
Deduct 0 from 89 and we're left with 89.
Grab the next digit (5) from the dividend, add it to 89, then carry on: 895 / 210

Let's proceed to step 8:
895 divided by 210 is 4 with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 191804.0
If we subtract 840 from 895, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 210 is 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 191804.2
Deduct 420 from 550 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
If we divide 1300 by 210, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 191804.26
If we subtract 1260 from 1300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 210, we get 1 and a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 191804.261
Subtract 210 from 400 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 12:
If we divide 1900 by 210, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 191804.2619
Subtract 1890 from 1900 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
If we divide 100 by 210, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 191804.2619
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.

Let's proceed to step 14:
When dividing 1000 by 210, we get 4 with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 191804.261904
Deduct 840 from 1000 and we're left 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 15:
When dividing 1600 by 210, we get 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 191804.2619047
If we take 1470 away from 1600, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
The number 210 fits into 1300 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 191804.26190476
The remainder is 40 after subtracting 1260 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 191804.26190476 with a remaining 4e-08.
