Let's divide 42981936 by 139
Let's see how many times 139 fits into 42981936.

Going ahead to step 1:
If we divide 4 by 139, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 139

Advancing to step 2:
139 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 139

Moving on to step 3:
When dividing 429 by 139, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 12 after subtracting 417 from 429.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 139

Moving on to step 4:
The number 139 fits into 128 0 times, leaving a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 128, we get 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 139

On to step 5:
The number 139 fits into 1281 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Deduct 1251 from 1281 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 139

On to step 6:
139 goes into 309 2 times with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 3092.0
Subtract 278 from 309 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 139

Let's proceed to step 7:
313 divided by 139 is 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 30922.0
Subtract 278 from 313 to get 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 139

Step 8:
139 can be fit into 356 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 309222.0
The remainder is 78 after subtracting 278 from 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
The number 139 fits into 780 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 309222.5
Subtract 695 from 780 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
The number 139 fits into 850 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 309222.56
If we take 834 away from 850, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
139 can be fit into 160 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 309222.561
The remainder is 21 after subtracting 139 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
139 can be fit into 210 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 309222.5611
If we take 139 away from 210, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 309222.5611 with a remaining 0.00071.
