We divide 61110071 by 20
We're looking to find how many times 20 goes into 61110071.

Advancing to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Advancing to step 2:
The number 20 fits into 61 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 61 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 20

Advancing to step 3:
The number 20 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 11, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 20

Advancing to step 4:
20 can be fit into 111 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 305.0
If we take 100 away from 111, we end up with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 20

Advancing to step 5:
When dividing 110 by 20, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055.0
The remainder is 10 after subtracting 100 from 110.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 20

Step 6:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 30555.0
If we subtract 100 from 100, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 20

On to step 7:
7 divided by 20 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 305550.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Moving on to step 8:
If we divide 71 by 20, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3055503.0
Deduct 60 from 71 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055503.5
Deduct 100 from 110 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3055503.55
Deduct 100 from 100 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.

The final result is 3055503.55 with a remainder of 0.0.
