We're dividing 10491942 by 603 
We're looking to find how many times 603 goes into 10491942.

Going ahead to step 1:
The number 603 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 603

On to step 2:
10 divided by 603 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 603

Advancing to step 3:
603 goes into 104 0 times with a remainder of 104.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 104, we end up with 104.
Include the next digit (9) from the dividend after 104, then repeat: 1049 / 603

On to step 4:
603 can be fit into 1049 1 times, resulting in a remainder of 446.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 446 after subtracting 603 from 1049.
Include the next digit (1) from the dividend after 446, then repeat: 4461 / 603

Moving on to step 5:
4461 divided by 603 is 7 with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 4221 away from 4461, we end up with 240.
Fetch the next digit (9) from the dividend, attach it to 240 and continue: 2409 / 603

Step 6:
603 can be fit into 2409 3 times, resulting in a remainder of 600.
The next digit of our result is 3. 
Result so far: 173.0
Deduct 1809 from 2409 and we're left with 600.
Include the next digit (4) from the dividend after 600, then repeat: 6004 / 603

On to step 7:
603 can be fit into 6004 9 times, resulting in a remainder of 577.
Put 9 as the next digit of the answer. 
Result so far: 1739.0
Subtracting 5427 from 6004 leaves us with 577.
Include the next digit (2) from the dividend after 577, then repeat: 5772 / 603

Step 8:
If we divide 5772 by 603, we get 9 and a remainder of 345.
The number 9 becomes the next digit in our result. 
Result so far: 17399.0
If we subtract 5427 from 5772, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 9:
603 goes into 3450 5 times with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 17399.5
The remainder is 435 after subtracting 3015 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 10:
603 can be fit into 4350 7 times, resulting in a remainder of 129.
The next digit of our result is 7. 
Result so far: 17399.57
If we take 4221 away from 4350, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 11:
603 goes into 1290 2 times with a remainder of 84.
The next digit of our result is 2. 
Result so far: 17399.572
Subtract 1206 from 1290 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
The number 603 fits into 840 1 times, leaving a remainder of 237.
Write down 1 as next digit of the result. 
Result so far: 17399.5721
If we take 603 away from 840, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 13:
When dividing 2370 by 603, we get 3 with a remainder of 561.
The number 3 becomes the next digit in our result. 
Result so far: 17399.57213
Subtracting 1809 from 2370 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 14:
5610 divided by 603 is 9 with a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 17399.572139
The remainder is 183 after subtracting 5427 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 15:
603 goes into 1830 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 17399.5721393
Subtracting 1809 from 1830 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 16:
603 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 17399.5721393
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 17399.5721393, with a leftover of 2.1e-07.
