We're dividing 988770 by 42 
We want to figure out the number of times 988770 can be divided by 42.

Advancing to step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 42

Advancing to step 2:
If we divide 98 by 42, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 14 after subtracting 84 from 98.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 42

Moving on to step 3:
42 can be fit into 148 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 126 away from 148, we end up with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 42

Step 4:
42 goes into 227 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
If we subtract 210 from 227, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 42

On to step 5:
177 divided by 42 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 2354.0
Subtract 168 from 177 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 42

Let's proceed to step 6:
90 divided by 42 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 23542.0
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 23542.1
If we subtract 42 from 60, we 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.

On to step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 23542.14
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 23542.142
Subtract 84 from 120 to get 36.
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 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 23542.1428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 23542.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 23542.142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 23542.1428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 42 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 23542.14285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 23542.14285714 with a remainder of 1.2e-08.
