79997534 divided by 42 
Our goal is to divide 79997534 by 42.

On to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 42

Let's proceed to step 2:
42 can be fit into 79 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 79 to get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 42

On to step 3:
The number 42 fits into 379 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 378 from 379 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

On to step 4:
42 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 42

Going ahead to step 5:
197 divided by 42 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1904.0
Subtract 168 from 197 to get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 42

Let's proceed to step 6:
When dividing 295 by 42, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 19047.0
Subtract 294 from 295 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 42

Let's proceed to step 7:
42 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 190470.0
If we subtract 0 from 13, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Step 8:
42 goes into 134 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 1904703.0
The remainder is 8 after subtracting 126 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1904703.1
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 1904703.19
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1904703.19
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1904703.1904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 1904703.19047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 42, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1904703.190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1904703.1904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
When dividing 380 by 42, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1904703.19047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 1904703.19047619 with a balance of 2e-09.
