42203478 ÷ 187 
We want to figure out the number of times 42203478 can be divided by 187.

Step 1:
If we divide 4 by 187, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 187

On to step 2:
When dividing 42 by 187, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 187

Going ahead to step 3:
The number 187 fits into 422 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 48 after subtracting 374 from 422.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 187

On to step 4:
480 divided by 187 is 2 with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 374 away from 480, we end up with 106.
Append the next digit (3) from the dividend to 106 and continue with: 1063 / 187

Let's proceed to step 5:
187 goes into 1063 5 times with a remainder of 128.
The next digit of our result is 5. 
Result so far: 225.0
Subtracting 935 from 1063 leaves us with 128.
Fetch the next digit (4) from the dividend, attach it to 128 and continue: 1284 / 187

Let's proceed to step 6:
If we divide 1284 by 187, we get 6 and a remainder of 162.
Put 6 as the next digit of the answer. 
Result so far: 2256.0
The remainder is 162 after subtracting 1122 from 1284.
Take the next digit (7) from the dividend and append it to 162, then repeat: 1627 / 187

Step 7:
187 goes into 1627 8 times with a remainder of 131.
The next digit of our result is 8. 
Result so far: 22568.0
If we subtract 1496 from 1627, we get 131.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 187

On to step 8:
1318 divided by 187 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 225687.0
The remainder is 9 after subtracting 1309 from 1318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
If we divide 90 by 187, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 225687.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
The number 187 fits into 900 4 times, leaving a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 225687.04
The remainder is 152 after subtracting 748 from 900.
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 11:
1520 divided by 187 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 225687.048
Subtract 1496 from 1520 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 187, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 225687.0481
If we subtract 187 from 240, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
When dividing 530 by 187, we get 2 with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 225687.04812
If we take 374 away from 530, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 14:
If we divide 1560 by 187, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 225687.048128
If we take 1496 away from 1560, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
187 goes into 640 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 225687.0481283
Subtract 561 from 640 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 16:
187 goes into 790 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 225687.04812834
Subtract 748 from 790 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 225687.04812834 with a remainder of 4.2e-08.
