We're dividing 4398398 by 425 
We want to figure out the number of times 4398398 can be divided by 425.

Going ahead to step 1:
425 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 425

Advancing to step 2:
If we divide 43 by 425, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 425

Step 3:
425 can be fit into 439 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 425 from 439 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 425

Advancing to step 4:
425 can be fit into 148 0 times, resulting in a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 148 to get 148.
Grab the next digit (3) from the dividend, add it to 148, then carry on: 1483 / 425

Going ahead to step 5:
When dividing 1483 by 425, we get 3 with a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 208 after subtracting 1275 from 1483.
Include the next digit (9) from the dividend after 208, then repeat: 2089 / 425

On to step 6:
The number 425 fits into 2089 4 times, leaving a remainder of 389.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
Subtracting 1700 from 2089 leaves us with 389.
Grab the next digit (8) from the dividend, add it to 389, then carry on: 3898 / 425

Step 7:
When dividing 3898 by 425, we get 9 with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 10349.0
If we subtract 3825 from 3898, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
730 divided by 425 is 1 with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 10349.1
The remainder is 305 after subtracting 425 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 9:
425 goes into 3050 7 times with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 10349.17
The remainder is 75 after subtracting 2975 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
425 goes into 750 1 times with a remainder of 325.
The next digit of our result is 1. 
Result so far: 10349.171
Subtract 425 from 750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 11:
The number 425 fits into 3250 7 times, leaving a remainder of 275.
Record the quotient 7 as the next digit in the result. 
Result so far: 10349.1717
If we take 2975 away from 3250, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 12:
When dividing 2750 by 425, we get 6 with a remainder of 200.
Put 6 as the next digit of the answer. 
Result so far: 10349.17176
The remainder is 200 after subtracting 2550 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
If we divide 2000 by 425, we get 4 and a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 10349.171764
If we subtract 1700 from 2000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
3000 divided by 425 is 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 10349.1717647
If we take 2975 away from 3000, we end up 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.

Going ahead to step 15:
If we divide 250 by 425, we get 0 and a remainder of 250.
The next digit of our result is 0. 
Result so far: 10349.1717647
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.

After the division, we end up with 10349.1717647 and a remainder of 2.5e-07.
