42221334 ÷ 39 
We want to figure out the number of times 42221334 can be divided by 39.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 39

Moving on to step 2:
The number 39 fits into 42 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 39 away from 42, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 39

Step 3:
When dividing 32 by 39, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 32, we end up with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 39

Advancing to step 4:
39 can be fit into 322 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 312 from 322 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 39

Step 5:
39 goes into 101 2 times with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 1082.0
Subtracting 78 from 101 leaves us with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 39

Going ahead to step 6:
233 divided by 39 is 5 with a remainder of 38.
The next digit of our result is 5. 
Result so far: 10825.0
If we subtract 195 from 233, we get 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 39

Moving on to step 7:
If we divide 383 by 39, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 108259.0
If we subtract 351 from 383, we get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 39

Step 8:
324 divided by 39 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1082598.0
If we subtract 312 from 324, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1082598.3
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 39, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 1082598.3
Deduct 0 from 30 and we're left 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.

Advancing to step 11:
The number 39 fits into 300 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 1082598.307
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1082598.3076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1082598.30769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 1082598.307692
Subtracting 78 from 90 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.

Advancing to step 15:
39 goes into 120 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1082598.3076923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 16:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1082598.3076923
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 1082598.3076923 with a remaining 3e-08.
