We're dividing 72107942 by 777 
Let's see how many times 777 fits into 72107942.

Step 1:
When dividing 7 by 777, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 777

Moving on to step 2:
72 divided by 777 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 777

Advancing to step 3:
777 can be fit into 721 0 times, resulting in a remainder of 721.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 721, we get 721.
Take the next digit (0) from the dividend and append it to 721, then repeat: 7210 / 777

On to step 4:
777 can be fit into 7210 9 times, resulting in a remainder of 217.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 6993 from 7210 leaves us with 217.
Fetch the next digit (7) from the dividend, attach it to 217 and continue: 2177 / 777

Advancing to step 5:
When dividing 2177 by 777, we get 2 with a remainder of 623.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we take 1554 away from 2177, we end up with 623.
Bring next digit (9) of the dividend behind the 623 and repeat the process: 6239 / 777

Going ahead to step 6:
6239 divided by 777 is 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 928.0
If we subtract 6216 from 6239, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 777

Moving on to step 7:
234 divided by 777 is 0 with a remainder of 234.
The next digit of our result is 0. 
Result so far: 9280.0
If we take 0 away from 234, we end up with 234.
Include the next digit (2) from the dividend after 234, then repeat: 2342 / 777

Advancing to step 8:
The number 777 fits into 2342 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 92803.0
If we subtract 2331 from 2342, 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.

Moving on to step 9:
110 divided by 777 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 92803.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
777 goes into 1100 1 times with a remainder of 323.
Record the quotient 1 as the next digit in the result. 
Result so far: 92803.01
Subtracting 777 from 1100 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 11:
777 goes into 3230 4 times with a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 92803.014
Deduct 3108 from 3230 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 12:
777 can be fit into 1220 1 times, resulting in a remainder of 443.
The number 1 becomes the next digit in our result. 
Result so far: 92803.0141
Deduct 777 from 1220 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 13:
777 goes into 4430 5 times with a remainder of 545.
The next digit of our result is 5. 
Result so far: 92803.01415
If we take 3885 away from 4430, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Going ahead to step 14:
5450 divided by 777 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 92803.014157
If we subtract 5439 from 5450, 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.

Moving on to step 15:
777 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 92803.014157
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
1100 divided by 777 is 1 with a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 92803.01415701
If we take 777 away from 1100, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

The final outcome is 92803.01415701, with a leftover of 3.23e-07.
