Let's divide 10198409 by 946
We want to figure out the number of times 10198409 can be divided by 946.

Step 1:
If we divide 1 by 946, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 946

Moving on to step 2:
10 divided by 946 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 946

Advancing to step 3:
946 goes into 101 0 times with a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 946

Going ahead to step 4:
If we divide 1019 by 946, we get 1 and a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 946 from 1019 to get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 946

Going ahead to step 5:
The number 946 fits into 738 0 times, leaving a remainder of 738.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 738 after subtracting 0 from 738.
Include the next digit (4) from the dividend after 738, then repeat: 7384 / 946

Advancing to step 6:
7384 divided by 946 is 7 with a remainder of 762.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtracting 6622 from 7384 leaves us with 762.
Fetch the next digit (0) from the dividend, attach it to 762 and continue: 7620 / 946

Step 7:
The number 946 fits into 7620 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1078.0
If we take 7568 away from 7620, we end up with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 946

Moving on to step 8:
529 divided by 946 is 0 with a remainder of 529.
Write down 0 as next digit of the result. 
Result so far: 10780.0
The remainder is 529 after subtracting 0 from 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 9:
946 can be fit into 5290 5 times, resulting in a remainder of 560.
Write down 5 as next digit of the result. 
Result so far: 10780.5
If we take 4730 away from 5290, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 10:
946 goes into 5600 5 times with a remainder of 870.
Record the quotient 5 as the next digit in the result. 
Result so far: 10780.55
Subtracting 4730 from 5600 leaves us with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

After the division, we end up with 10780.55 and a remainder of 0.87.
