We look at the division of 45732370 by 42 
Let's see how many times 42 fits into 45732370.

Moving on to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

Going ahead to step 2:
45 divided by 42 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 45 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 42

Advancing to step 3:
42 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 42

Advancing to step 4:
373 divided by 42 is 8 with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we take 336 away from 373, we end up with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 42

Step 5:
372 divided by 42 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1088.0
If we take 336 away from 372, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 42

Step 6:
42 can be fit into 363 8 times, resulting in a remainder of 27.
The next digit of our result is 8. 
Result so far: 10888.0
Subtract 336 from 363 to get 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 42

Going ahead to step 7:
If we divide 277 by 42, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 108886.0
Subtracting 252 from 277 leaves us with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 42

Going ahead to step 8:
If we divide 250 by 42, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 1088865.0
If we subtract 210 from 250, we 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.

Going ahead to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 1088865.9
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1088865.95
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1088865.952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
42 goes into 160 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 1088865.9523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
42 goes into 340 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1088865.95238
Subtracting 336 from 340 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.

On to step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1088865.95238
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 15:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1088865.9523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1088865.95238095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 1088865.95238095, with a leftover of 1e-08.
