We're dividing 3878212 by 425 
Our goal is to divide 3878212 by 425.

On to step 1:
When dividing 3 by 425, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 425

Step 2:
If we divide 38 by 425, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 425

On to step 3:
387 divided by 425 is 0 with a remainder of 387.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 387 leaves us with 387.
Bring next digit (8) of the dividend behind the 387 and repeat the process: 3878 / 425

On to step 4:
425 can be fit into 3878 9 times, resulting in a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 3825 from 3878 and we're left with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 425

Moving on to step 5:
425 can be fit into 532 1 times, resulting in a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 425 from 532 to get 107.
Grab the next digit (1) from the dividend, add it to 107, then carry on: 1071 / 425

Advancing to step 6:
When dividing 1071 by 425, we get 2 with a remainder of 221.
Put 2 as the next digit of the answer. 
Result so far: 912.0
If we subtract 850 from 1071, we get 221.
Grab the next digit (2) from the dividend, add it to 221, then carry on: 2212 / 425

Moving on to step 7:
If we divide 2212 by 425, we get 5 and a remainder of 87.
Use 5 as the next digit of our solution. 
Result so far: 9125.0
If we subtract 2125 from 2212, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 8:
425 can be fit into 870 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9125.2
If we subtract 850 from 870, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
425 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 9125.2
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
2000 divided by 425 is 4 with a remainder of 300.
The next digit of our result is 4. 
Result so far: 9125.204
If we take 1700 away from 2000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
The number 425 fits into 3000 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 9125.2047
Deduct 2975 from 3000 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
If we divide 250 by 425, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 9125.2047
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
2500 divided by 425 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 9125.204705
Subtracting 2125 from 2500 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 14:
425 goes into 3750 8 times with a remainder of 350.
Record the quotient 8 as the next digit in the result. 
Result so far: 9125.2047058
The remainder is 350 after subtracting 3400 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 15:
When dividing 3500 by 425, we get 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 9125.20470588
If we subtract 3400 from 3500, 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.

The quotient of the division is 9125.20470588, and the remainder is 1e-07.
