We look at the division of 78038534 by 91 
Let's see how many times 91 fits into 78038534.

Going ahead to step 1:
When dividing 7 by 91, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 91

Moving on to step 2:
91 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 91

Let's proceed to step 3:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 728 from 780 and we're left with 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 91

Going ahead to step 4:
91 goes into 523 5 times with a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 455 from 523 leaves us with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 91

Let's proceed to step 5:
688 divided by 91 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 857.0
Subtracting 637 from 688 leaves us with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 91

Let's proceed to step 6:
When dividing 515 by 91, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 8575.0
If we take 455 away from 515, we end up with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 91

Let's proceed to step 7:
603 divided by 91 is 6 with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 85756.0
If we subtract 546 from 603, we get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 91

Going ahead to step 8:
91 goes into 574 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 857566.0
If we subtract 546 from 574, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 91 fits into 280 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 857566.3
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
If we divide 70 by 91, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 857566.3
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
When dividing 700 by 91, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 857566.307
If we take 637 away from 700, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
630 divided by 91 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 857566.3076
Subtracting 546 from 630 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
91 goes into 840 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 857566.30769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
91 goes into 210 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 857566.307692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
280 divided by 91 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 857566.3076923
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
If we divide 70 by 91, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 857566.3076923
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 857566.3076923, and the remainder is 7e-08.
