77890137 divided by 848 
Our goal is to divide 77890137 by 848.

Let's proceed to step 1:
7 divided by 848 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 848

Let's proceed to step 2:
77 divided by 848 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 848

Step 3:
When dividing 778 by 848, we get 0 with a remainder of 778.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 778 to get 778.
Grab the next digit (9) from the dividend, add it to 778, then carry on: 7789 / 848

Advancing to step 4:
The number 848 fits into 7789 9 times, leaving a remainder of 157.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7632 from 7789 to get 157.
Grab the next digit (0) from the dividend, add it to 157, then carry on: 1570 / 848

Moving on to step 5:
848 goes into 1570 1 times with a remainder of 722.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 848 from 1570 and we're left with 722.
Append the next digit (1) from the dividend to 722 and continue with: 7221 / 848

Step 6:
848 can be fit into 7221 8 times, resulting in a remainder of 437.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
If we take 6784 away from 7221, we end up with 437.
Fetch the next digit (3) from the dividend, attach it to 437 and continue: 4373 / 848

Let's proceed to step 7:
4373 divided by 848 is 5 with a remainder of 133.
Record the quotient 5 as the next digit in the result. 
Result so far: 9185.0
If we subtract 4240 from 4373, we get 133.
Take the next digit (7) from the dividend and append it to 133, then repeat: 1337 / 848

Step 8:
848 goes into 1337 1 times with a remainder of 489.
The next digit of our result is 1. 
Result so far: 91851.0
The remainder is 489 after subtracting 848 from 1337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
If we divide 4890 by 848, we get 5 and a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 91851.5
If we subtract 4240 from 4890, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
6500 divided by 848 is 7 with a remainder of 564.
Put 7 as the next digit of the answer. 
Result so far: 91851.57
The remainder is 564 after subtracting 5936 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 11:
848 goes into 5640 6 times with a remainder of 552.
Use 6 as the next digit of our solution. 
Result so far: 91851.576
Subtract 5088 from 5640 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 12:
848 can be fit into 5520 6 times, resulting in a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 91851.5766
If we subtract 5088 from 5520, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final outcome is 91851.5766, with a leftover of 0.00432.
