99889970 ÷ 139 
We're looking to find how many times 139 goes into 99889970.

On to step 1:
The number 139 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 139

On to step 2:
When dividing 99 by 139, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 139

Advancing to step 3:
When dividing 998 by 139, we get 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 25 after subtracting 973 from 998.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 139

Going ahead to step 4:
139 goes into 258 1 times with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 139 from 258 to get 119.
Fetch the next digit (9) from the dividend, attach it to 119 and continue: 1199 / 139

Step 5:
1199 divided by 139 is 8 with a remainder of 87.
Write down 8 as next digit of the result. 
Result so far: 718.0
The remainder is 87 after subtracting 1112 from 1199.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 139

Advancing to step 6:
139 can be fit into 879 6 times, resulting in a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 7186.0
Subtract 834 from 879 to get 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 139

Moving on to step 7:
The number 139 fits into 457 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 71863.0
If we take 417 away from 457, we end up with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 139

Going ahead to step 8:
139 can be fit into 400 2 times, resulting in a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 718632.0
The remainder is 122 after subtracting 278 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
If we divide 1220 by 139, we get 8 and a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 718632.8
Subtracting 1112 from 1220 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
139 can be fit into 1080 7 times, resulting in a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 718632.87
The remainder is 107 after subtracting 973 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 11:
When dividing 1070 by 139, we get 7 with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 718632.877
Subtracting 973 from 1070 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The quotient of the division is 718632.877, and the remainder is 0.0097.
