29278629 divided by 139 
We want to figure out the number of times 29278629 can be divided by 139.

On to step 1:
When dividing 2 by 139, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 139

Moving on to step 2:
The number 139 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 139

Moving on to step 3:
139 can be fit into 292 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 278 away from 292, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 139

Moving on to step 4:
If we divide 147 by 139, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 139 from 147 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 139

Let's proceed to step 5:
139 can be fit into 88 0 times, resulting in a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
The remainder is 88 after subtracting 0 from 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 139

Going ahead to step 6:
139 can be fit into 886 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 2106.0
If we take 834 away from 886, we end up with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 139

Step 7:
139 can be fit into 522 3 times, resulting in a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 21063.0
Subtracting 417 from 522 leaves us with 105.
Take the next digit (9) from the dividend and append it to 105, then repeat: 1059 / 139

Let's proceed to step 8:
139 can be fit into 1059 7 times, resulting in a remainder of 86.
Use 7 as the next digit of our solution. 
Result so far: 210637.0
If we take 973 away from 1059, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
860 divided by 139 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 210637.6
Deduct 834 from 860 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
If we divide 260 by 139, we get 1 and a remainder of 121.
Write down 1 as next digit of the result. 
Result so far: 210637.61
Deduct 139 from 260 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 11:
139 can be fit into 1210 8 times, resulting in a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 210637.618
The remainder is 98 after subtracting 1112 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
If we divide 980 by 139, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 210637.6187
The remainder is 7 after subtracting 973 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
139 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 210637.6187
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
139 goes into 700 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 210637.618705
If we subtract 695 from 700, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 15:
When dividing 50 by 139, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 210637.618705
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
500 divided by 139 is 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 210637.61870503
Deduct 417 from 500 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 210637.61870503 and a remainder of 8.3e-08.
