We divide 40378207 by 402
Let's see how many times 402 fits into 40378207.

Advancing to step 1:
402 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 402

Going ahead to step 2:
402 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 402

Going ahead to step 3:
403 divided by 402 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 402 from 403 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 402

Step 4:
If we divide 17 by 402, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 17, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 402

Step 5:
402 goes into 178 0 times with a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 178, we end up with 178.
Bring next digit (2) of the dividend behind the 178 and repeat the process: 1782 / 402

Going ahead to step 6:
1782 divided by 402 is 4 with a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
The remainder is 174 after subtracting 1608 from 1782.
Bring next digit (0) of the dividend behind the 174 and repeat the process: 1740 / 402

Going ahead to step 7:
The number 402 fits into 1740 4 times, leaving a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 10044.0
If we take 1608 away from 1740, we end up with 132.
Append the next digit (7) from the dividend to 132 and continue with: 1327 / 402

Step 8:
1327 divided by 402 is 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 100443.0
Subtracting 1206 from 1327 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 9:
The number 402 fits into 1210 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 100443.3
Subtracting 1206 from 1210 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 402, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 100443.3
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 402, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 100443.3
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 100443.3 and a remainder of 0.04.
