We look at the division of 90001142 by 777 
Let's see how many times 777 fits into 90001142.

Step 1:
When dividing 9 by 777, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 777

Step 2:
90 divided by 777 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 777

Going ahead to step 3:
The number 777 fits into 900 1 times, leaving a remainder of 123.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 777 from 900 and we're left with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 777

Step 4:
The number 777 fits into 1230 1 times, leaving a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 777 from 1230, we get 453.
Grab the next digit (1) from the dividend, add it to 453, then carry on: 4531 / 777

Let's proceed to step 5:
4531 divided by 777 is 5 with a remainder of 646.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Deduct 3885 from 4531 and we're left with 646.
Bring next digit (1) of the dividend behind the 646 and repeat the process: 6461 / 777

Moving on to step 6:
777 goes into 6461 8 times with a remainder of 245.
Write down 8 as next digit of the result. 
Result so far: 1158.0
Deduct 6216 from 6461 and we're left with 245.
Bring next digit (4) of the dividend behind the 245 and repeat the process: 2454 / 777

Going ahead to step 7:
If we divide 2454 by 777, we get 3 and a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 11583.0
Deduct 2331 from 2454 and we're left with 123.
Grab the next digit (2) from the dividend, add it to 123, then carry on: 1232 / 777

Going ahead to step 8:
1232 divided by 777 is 1 with a remainder of 455.
Write down 1 as next digit of the result. 
Result so far: 115831.0
Deduct 777 from 1232 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 9:
777 goes into 4550 5 times with a remainder of 665.
Use 5 as the next digit of our solution. 
Result so far: 115831.5
If we subtract 3885 from 4550, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 10:
6650 divided by 777 is 8 with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 115831.58
Deduct 6216 from 6650 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 11:
When dividing 4340 by 777, we get 5 with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 115831.585
Subtracting 3885 from 4340 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 12:
The number 777 fits into 4550 5 times, leaving a remainder of 665.
The number 5 becomes the next digit in our result. 
Result so far: 115831.5855
If we subtract 3885 from 4550, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

The final outcome is 115831.5855, with a leftover of 0.00665.
