Let's divide 21196642 by 139
Our goal is to divide 21196642 by 139.

Moving on to step 1:
If we divide 2 by 139, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 139

Step 2:
139 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 139

Going ahead to step 3:
The number 139 fits into 211 1 times, leaving a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 139 from 211 to get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 139

Moving on to step 4:
When dividing 729 by 139, we get 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 695 from 729, we get 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 139

Step 5:
When dividing 346 by 139, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 68 after subtracting 278 from 346.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 139

Moving on to step 6:
139 can be fit into 686 4 times, resulting in a remainder of 130.
The next digit of our result is 4. 
Result so far: 1524.0
Subtracting 556 from 686 leaves us with 130.
Append the next digit (4) from the dividend to 130 and continue with: 1304 / 139

Step 7:
The number 139 fits into 1304 9 times, leaving a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 15249.0
Deduct 1251 from 1304 and we're left with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 139

Step 8:
139 can be fit into 532 3 times, resulting in a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 152493.0
If we take 417 away from 532, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
139 goes into 1150 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 152493.8
Deduct 1112 from 1150 and we're left 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.

Advancing to step 10:
380 divided by 139 is 2 with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 152493.82
If we take 278 away from 380, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 11:
The number 139 fits into 1020 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 152493.827
If we take 973 away from 1020, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
The number 139 fits into 470 3 times, leaving a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 152493.8273
Subtract 417 from 470 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
530 divided by 139 is 3 with a remainder of 113.
Put 3 as the next digit of the answer. 
Result so far: 152493.82733
Deduct 417 from 530 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Our division results in 152493.82733 with a remaining 0.000113.
