Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 989

On to step 2:
The number 989 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 989

Step 3:
989 can be fit into 421 0 times, resulting in a remainder of 421.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 421 to get 421.
Take the next digit (6) from the dividend and append it to 421, then repeat: 4216 / 989

Let's proceed to step 4:
4216 divided by 989 is 4 with a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3956 away from 4216, we end up with 260.
Fetch the next digit (3) from the dividend, attach it to 260 and continue: 2603 / 989

Let's proceed to step 5:
2603 divided by 989 is 2 with a remainder of 625.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 1978 from 2603 and we're left with 625.
Grab the next digit (4) from the dividend, add it to 625, then carry on: 6254 / 989

On to step 6:
When dividing 6254 by 989, we get 6 with a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
If we take 5934 away from 6254, we end up with 320.
Append the next digit (3) from the dividend to 320 and continue with: 3203 / 989

Moving on to step 7:
989 can be fit into 3203 3 times, resulting in a remainder of 236.
Put 3 as the next digit of the answer. 
Result so far: 4263.0
The remainder is 236 after subtracting 2967 from 3203.
Grab the next digit (9) from the dividend, add it to 236, then carry on: 2369 / 989

Step 8:
If we divide 2369 by 989, we get 2 and a remainder of 391.
Write down 2 as next digit of the result. 
Result so far: 42632.0
If we take 1978 away from 2369, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
When dividing 3910 by 989, we get 3 with a remainder of 943.
Write down 3 as next digit of the result. 
Result so far: 42632.3
The remainder is 943 after subtracting 2967 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Advancing to step 10:
When dividing 9430 by 989, we get 9 with a remainder of 529.
Use 9 as the next digit of our solution. 
Result so far: 42632.39
The remainder is 529 after subtracting 8901 from 9430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 11:
The number 989 fits into 5290 5 times, leaving a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 42632.395
The remainder is 345 after subtracting 4945 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 12:
989 goes into 3450 3 times with a remainder of 483.
Put 3 as the next digit of the answer. 
Result so far: 42632.3953
Subtract 2967 from 3450 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 13:
If we divide 4830 by 989, we get 4 and a remainder of 874.
Write down 4 as next digit of the result. 
Result so far: 42632.39534
If we take 3956 away from 4830, we end up with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Step 14:
989 can be fit into 8740 8 times, resulting in a remainder of 828.
Write down 8 as next digit of the result. 
Result so far: 42632.395348
If we subtract 7912 from 8740, we get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Moving on to step 15:
The number 989 fits into 8280 8 times, leaving a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 42632.3953488
Subtract 7912 from 8280 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 42632.3953488, and the remainder is 3.68e-06.
