42157086 divided by 919 
Let's see how many times 919 fits into 42157086.

On to step 1:
If we divide 4 by 919, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
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 / 919

Advancing to step 2:
The number 919 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
If we subtract 0 from 42, we get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 919

Advancing to step 3:
When dividing 421 by 919, we get 0 with a remainder of 421.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Include the next digit (5) from the dividend after 421, then repeat: 4215 / 919

Advancing to step 4:
If we divide 4215 by 919, we get 4 and a remainder of 539.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 539 after subtracting 3676 from 4215.
Bring next digit (7) of the dividend behind the 539 and repeat the process: 5397 / 919

Advancing to step 5:
When dividing 5397 by 919, we get 5 with a remainder of 802.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 4595 from 5397 leaves us with 802.
Take the next digit (0) from the dividend and append it to 802, then repeat: 8020 / 919

Going ahead to step 6:
919 goes into 8020 8 times with a remainder of 668.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
If we take 7352 away from 8020, we end up with 668.
Append the next digit (8) from the dividend to 668 and continue with: 6688 / 919

Moving on to step 7:
6688 divided by 919 is 7 with a remainder of 255.
The next digit of our result is 7. 
Result so far: 4587.0
If we take 6433 away from 6688, we end up with 255.
Include the next digit (6) from the dividend after 255, then repeat: 2556 / 919

Advancing to step 8:
2556 divided by 919 is 2 with a remainder of 718.
Put 2 as the next digit of the answer. 
Result so far: 45872.0
The remainder is 718 after subtracting 1838 from 2556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 9:
The number 919 fits into 7180 7 times, leaving a remainder of 747.
The number 7 becomes the next digit in our result. 
Result so far: 45872.7
If we subtract 6433 from 7180, we get 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

On to step 10:
When dividing 7470 by 919, we get 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 45872.78
The remainder is 118 after subtracting 7352 from 7470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
1180 divided by 919 is 1 with a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 45872.781
Subtract 919 from 1180 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 12:
919 goes into 2610 2 times with a remainder of 772.
Write down 2 as next digit of the result. 
Result so far: 45872.7812
The remainder is 772 after subtracting 1838 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 13:
919 can be fit into 7720 8 times, resulting in a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 45872.78128
Subtracting 7352 from 7720 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 14:
The number 919 fits into 3680 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 45872.781284
Subtracting 3676 from 3680 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
919 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 45872.781284
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
If we divide 400 by 919, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 45872.781284
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 45872.781284, with a leftover of 4e-07.
