We look at the division of 15941043 by 77 
Let's see how many times 77 fits into 15941043.

Going ahead to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 77

Let's proceed to step 2:
If we divide 15 by 77, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 77

Advancing to step 3:
77 can be fit into 159 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 154 from 159 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 77

Advancing to step 4:
77 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 77

Let's proceed to step 5:
77 goes into 541 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we subtract 539 from 541, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 77

Step 6:
When dividing 20 by 77, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2070.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 77

Going ahead to step 7:
204 divided by 77 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 20702.0
Subtracting 154 from 204 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 77

Step 8:
If we divide 503 by 77, we get 6 and a remainder of 41.
The next digit of our result is 6. 
Result so far: 207026.0
If we subtract 462 from 503, 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.

Going ahead to step 9:
410 divided by 77 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 207026.5
Subtract 385 from 410 to get 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 10:
250 divided by 77 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 207026.53
Subtract 231 from 250 to get 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 11:
If we divide 190 by 77, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 207026.532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 77 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 207026.5324
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
If we divide 520 by 77, we get 6 and a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 207026.53246
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.

Going ahead to step 14:
When dividing 580 by 77, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 207026.532467
Deduct 539 from 580 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 15:
410 divided by 77 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 207026.5324675
Subtract 385 from 410 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
The number 77 fits into 250 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 207026.53246753
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 207026.53246753, with a leftover of 1.9e-08.
