Let's divide 155420 by 91
Our goal is to divide 155420 by 91.

Going ahead to step 1:
If we divide 1 by 91, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
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 / 91

Step 2:
If we divide 15 by 91, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 91

Let's proceed to step 3:
155 divided by 91 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 91 away from 155, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 91

On to step 4:
If we divide 644 by 91, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 7 after subtracting 637 from 644.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 91

Step 5:
72 divided by 91 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 170.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 91

Let's proceed to step 6:
The number 91 fits into 720 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 1707.0
Subtracting 637 from 720 leaves us 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 7:
When dividing 830 by 91, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1707.9
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
91 goes into 110 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1707.91
If we take 91 away from 110, we end up 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.

Going ahead to step 9:
When dividing 190 by 91, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1707.912
Subtract 182 from 190 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 91, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1707.912
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
91 goes into 800 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 1707.91208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
720 divided by 91 is 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.912087
Subtracting 637 from 720 leaves us 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.

Moving on to step 13:
91 goes into 830 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1707.9120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 91 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1707.91208791
Deduct 91 from 110 and we're left 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.

The final outcome is 1707.91208791, with a leftover of 1.9e-08.
