We look at the division of 9153997 by 770 
Our goal is to divide 9153997 by 770.

On to step 1:
9 divided by 770 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 770

Going ahead to step 2:
The number 770 fits into 91 0 times, leaving a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 770

On to step 3:
If we divide 915 by 770, we get 1 and a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 770 away from 915, we end up with 145.
Bring next digit (3) of the dividend behind the 145 and repeat the process: 1453 / 770

Let's proceed to step 4:
770 can be fit into 1453 1 times, resulting in a remainder of 683.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 770 from 1453, we get 683.
Grab the next digit (9) from the dividend, add it to 683, then carry on: 6839 / 770

On to step 5:
If we divide 6839 by 770, we get 8 and a remainder of 679.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtract 6160 from 6839 to get 679.
Take the next digit (9) from the dividend and append it to 679, then repeat: 6799 / 770

Moving on to step 6:
6799 divided by 770 is 8 with a remainder of 639.
Put 8 as the next digit of the answer. 
Result so far: 1188.0
If we take 6160 away from 6799, we end up with 639.
Fetch the next digit (7) from the dividend, attach it to 639 and continue: 6397 / 770

Going ahead to step 7:
770 can be fit into 6397 8 times, resulting in a remainder of 237.
Write down 8 as next digit of the result. 
Result so far: 11888.0
The remainder is 237 after subtracting 6160 from 6397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 8:
770 can be fit into 2370 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 11888.3
Deduct 2310 from 2370 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
770 goes into 600 0 times with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 11888.3
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
6000 divided by 770 is 7 with a remainder of 610.
Use 7 as the next digit of our solution. 
Result so far: 11888.307
Subtracting 5390 from 6000 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
6100 divided by 770 is 7 with a remainder of 710.
Write down 7 as next digit of the result. 
Result so far: 11888.3077
If we take 5390 away from 6100, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final outcome is 11888.3077, with a leftover of 0.0071.
