We look at the division of 7786691 by 139 
Our goal is to divide 7786691 by 139.

Going ahead to step 1:
139 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 139

On to step 2:
139 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 139

Advancing to step 3:
The number 139 fits into 778 5 times, leaving a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 695 from 778, we get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 139

Let's proceed to step 4:
If we divide 836 by 139, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 834 from 836, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 139

Going ahead to step 5:
26 divided by 139 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 560.0
If we subtract 0 from 26, we get 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 139

Advancing to step 6:
139 goes into 269 1 times with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 5601.0
The remainder is 130 after subtracting 139 from 269.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 139

On to step 7:
The number 139 fits into 1301 9 times, leaving a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 56019.0
Deduct 1251 from 1301 and we're left 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.

Moving on to step 8:
139 goes into 500 3 times with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 56019.3
If we take 417 away from 500, we end up 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.

Advancing to step 9:
If we divide 830 by 139, we get 5 and a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 56019.35
If we take 695 away from 830, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
1350 divided by 139 is 9 with a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 56019.359
If we take 1251 away from 1350, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 11:
When dividing 990 by 139, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 56019.3597
If we take 973 away from 990, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
139 goes into 170 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 56019.35971
The remainder is 31 after subtracting 139 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
310 divided by 139 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 56019.359712
Subtracting 278 from 310 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 139, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 56019.3597122
Deduct 278 from 320 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 56019.3597122 with a balance of 4.2e-07.
