We're dividing 42837521 by 403 
We want to figure out the number of times 42837521 can be divided by 403.

Advancing to step 1:
403 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 403

Step 2:
The number 403 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 403

Moving on to step 3:
403 can be fit into 428 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 403 from 428 leaves us with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 403

Let's proceed to step 4:
403 goes into 253 0 times with a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 253 to get 253.
Bring next digit (7) of the dividend behind the 253 and repeat the process: 2537 / 403

Step 5:
2537 divided by 403 is 6 with a remainder of 119.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 119 after subtracting 2418 from 2537.
Bring next digit (5) of the dividend behind the 119 and repeat the process: 1195 / 403

Advancing to step 6:
The number 403 fits into 1195 2 times, leaving a remainder of 389.
The next digit of our result is 2. 
Result so far: 1062.0
Subtracting 806 from 1195 leaves us with 389.
Grab the next digit (2) from the dividend, add it to 389, then carry on: 3892 / 403

Step 7:
3892 divided by 403 is 9 with a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 10629.0
Subtract 3627 from 3892 to get 265.
Include the next digit (1) from the dividend after 265, then repeat: 2651 / 403

Step 8:
2651 divided by 403 is 6 with a remainder of 233.
The next digit of our result is 6. 
Result so far: 106296.0
If we subtract 2418 from 2651, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
The number 403 fits into 2330 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 106296.5
Subtracting 2015 from 2330 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 10:
403 can be fit into 3150 7 times, resulting in a remainder of 329.
Write down 7 as next digit of the result. 
Result so far: 106296.57
Deduct 2821 from 3150 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 11:
If we divide 3290 by 403, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 106296.578
If we take 3224 away from 3290, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
403 goes into 660 1 times with a remainder of 257.
Record the quotient 1 as the next digit in the result. 
Result so far: 106296.5781
Deduct 403 from 660 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 13:
2570 divided by 403 is 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 106296.57816
If we take 2418 away from 2570, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
403 goes into 1520 3 times with a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 106296.578163
If we take 1209 away from 1520, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 15:
The number 403 fits into 3110 7 times, leaving a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 106296.5781637
If we subtract 2821 from 3110, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 16:
The number 403 fits into 2890 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 106296.57816377
The remainder is 69 after subtracting 2821 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 106296.57816377 with a remainder of 6.9e-08.
