42985491 ÷ 49 
Our goal is to divide 42985491 by 49.

Advancing to step 1:
If we divide 4 by 49, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 49

Let's proceed to step 2:
The number 49 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 49

Moving on to step 3:
429 divided by 49 is 8 with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 37 after subtracting 392 from 429.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 49

Advancing to step 4:
When dividing 378 by 49, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 343 from 378 and we're left with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 49

On to step 5:
The number 49 fits into 355 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 877.0
Subtract 343 from 355 to get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 49

Going ahead to step 6:
124 divided by 49 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 8772.0
The remainder is 26 after subtracting 98 from 124.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 49

Going ahead to step 7:
The number 49 fits into 269 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 87725.0
If we subtract 245 from 269, we get 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 49

On to step 8:
49 can be fit into 241 4 times, resulting in a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 877254.0
Subtracting 196 from 241 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
The number 49 fits into 450 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 877254.9
Subtract 441 from 450 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
90 divided by 49 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 877254.91
If we take 49 away from 90, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
If we divide 410 by 49, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 877254.918
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 49, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 877254.9183
Subtracting 147 from 180 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
49 goes into 330 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 877254.91836
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
49 can be fit into 360 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 877254.918367
Deduct 343 from 360 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 15:
49 goes into 170 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 877254.9183673
Subtracting 147 from 170 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 16:
The number 49 fits into 230 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 877254.91836734
Deduct 196 from 230 and we're left 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.

The quotient of the division is 877254.91836734, and the remainder is 3.4e-08.
