We divide 42548187 by 312
We want to divide 42548187 by 312.

Moving on to step 1:
312 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 312

Advancing to step 2:
The number 312 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 312

Moving on to step 3:
When dividing 425 by 312, we get 1 with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 312 from 425 leaves us with 113.
Grab the next digit (4) from the dividend, add it to 113, then carry on: 1134 / 312

Going ahead to step 4:
1134 divided by 312 is 3 with a remainder of 198.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 936 from 1134, we get 198.
Append the next digit (8) from the dividend to 198 and continue with: 1988 / 312

Let's proceed to step 5:
1988 divided by 312 is 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtracting 1872 from 1988 leaves us with 116.
Take the next digit (1) from the dividend and append it to 116, then repeat: 1161 / 312

Advancing to step 6:
312 can be fit into 1161 3 times, resulting in a remainder of 225.
Record the quotient 3 as the next digit in the result. 
Result so far: 1363.0
Deduct 936 from 1161 and we're left with 225.
Include the next digit (8) from the dividend after 225, then repeat: 2258 / 312

On to step 7:
When dividing 2258 by 312, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 13637.0
Subtract 2184 from 2258 to get 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 312

Advancing to step 8:
The number 312 fits into 747 2 times, leaving a remainder of 123.
Put 2 as the next digit of the answer. 
Result so far: 136372.0
Subtract 624 from 747 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
312 can be fit into 1230 3 times, resulting in a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 136372.3
If we subtract 936 from 1230, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
2940 divided by 312 is 9 with a remainder of 132.
The next digit of our result is 9. 
Result so far: 136372.39
The remainder is 132 after subtracting 2808 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
If we divide 1320 by 312, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 136372.394
Deduct 1248 from 1320 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
720 divided by 312 is 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 136372.3942
The remainder is 96 after subtracting 624 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
312 can be fit into 960 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 136372.39423
The remainder is 24 after subtracting 936 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 312 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 136372.39423
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
If we divide 2400 by 312, we get 7 and a remainder of 216.
Put 7 as the next digit of the answer. 
Result so far: 136372.3942307
If we subtract 2184 from 2400, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
2160 divided by 312 is 6 with a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 136372.39423076
Deduct 1872 from 2160 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 136372.39423076, and the remainder is 2.88e-07.
