We look at the division of 13945445 by 77 
We want to figure out the number of times 13945445 can be divided by 77.

Let's proceed to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 77

Step 2:
When dividing 13 by 77, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 77

Step 3:
139 divided by 77 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 77 away from 139, we end up with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 77

Moving on to step 4:
624 divided by 77 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 616 from 624 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 77

Step 5:
If we divide 85 by 77, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Deduct 77 from 85 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 77

Advancing to step 6:
When dividing 84 by 77, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1811.0
Subtracting 77 from 84 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 77

Step 7:
74 divided by 77 is 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 18110.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 77

Going ahead to step 8:
77 goes into 745 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 181109.0
Subtracting 693 from 745 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
77 can be fit into 520 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 181109.6
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
77 goes into 580 7 times with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 181109.67
Subtract 539 from 580 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
77 can be fit into 410 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 181109.675
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
77 goes into 250 3 times with a remainder of 19.
The next digit of our result is 3. 
Result so far: 181109.6753
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
190 divided by 77 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 181109.67532
Deduct 154 from 190 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 77, we get 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 181109.675324
If we take 308 away from 360, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
77 can be fit into 520 6 times, resulting in a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 181109.6753246
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 16:
77 can be fit into 580 7 times, resulting in a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 181109.67532467
If we subtract 539 from 580, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 181109.67532467, with a leftover of 4.1e-08.
