91870203 ÷ 6 
Our goal is to divide 91870203 by 6.

Step 1:
When dividing 9 by 6, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 6 from 9 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 6

Let's proceed to step 2:
When dividing 31 by 6, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 30 away from 31, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 6

Moving on to step 3:
When dividing 18 by 6, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 153.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 6

Going ahead to step 4:
7 divided by 6 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1531.0
Deduct 6 from 7 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 6

Let's proceed to step 5:
If we divide 10 by 6, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 15311.0
If we subtract 6 from 10, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 6

On to step 6:
If we divide 42 by 6, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 153117.0
If we take 42 away from 42, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 6

On to step 7:
6 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1531170.0
Subtract 0 from 0 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 6

Advancing to step 8:
If we divide 3 by 6, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 15311700.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
30 divided by 6 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15311700.5
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
6 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15311700.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15311700.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15311700.5, with a leftover of 0.0.
