7103858 ÷ 139 
We want to figure out the number of times 7103858 can be divided by 139.

Let's proceed to step 1:
The number 139 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 139

Step 2:
139 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 139

Let's proceed to step 3:
139 goes into 710 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 695 from 710 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 139

Going ahead to step 4:
153 divided by 139 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 139 from 153 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 139

Going ahead to step 5:
139 goes into 148 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 511.0
If we take 139 away from 148, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 139

Moving on to step 6:
95 divided by 139 is 0 with a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 5110.0
Subtracting 0 from 95 leaves us with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 139

Moving on to step 7:
958 divided by 139 is 6 with a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 51106.0
If we subtract 834 from 958, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 8:
139 can be fit into 1240 8 times, resulting in a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 51106.8
If we subtract 1112 from 1240, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
If we divide 1280 by 139, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 51106.89
If we subtract 1251 from 1280, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 139, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 51106.892
Deduct 278 from 290 and we're left 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.

On to step 11:
139 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 51106.892
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
1200 divided by 139 is 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 51106.89208
The remainder is 88 after subtracting 1112 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 13:
880 divided by 139 is 6 with a remainder of 46.
The next digit of our result is 6. 
Result so far: 51106.892086
Deduct 834 from 880 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
The number 139 fits into 460 3 times, leaving a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 51106.8920863
Subtracting 417 from 460 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 15:
139 goes into 430 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 51106.89208633
The remainder is 13 after subtracting 417 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 51106.89208633, and the remainder is 1.3e-08.
