We're dividing 76612121 by 91 
We want to figure out the number of times 76612121 can be divided by 91.

Let's proceed to step 1:
7 divided by 91 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 91

Advancing to step 2:
91 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 91

Step 3:
If we divide 766 by 91, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 38 after subtracting 728 from 766.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 91

Moving on to step 4:
The number 91 fits into 381 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 84.0
If we take 364 away from 381, we end up with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 91

Moving on to step 5:
91 goes into 172 1 times with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 841.0
Deduct 91 from 172 and we're left with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 91

Let's proceed to step 6:
91 can be fit into 811 8 times, resulting in a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 8418.0
The remainder is 83 after subtracting 728 from 811.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 91

Going ahead to step 7:
The number 91 fits into 832 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 84189.0
Subtract 819 from 832 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 91

Let's proceed to step 8:
If we divide 131 by 91, we get 1 and a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 841891.0
If we take 91 away from 131, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 841891.4
Deduct 364 from 400 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
91 can be fit into 360 3 times, resulting in a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 841891.43
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 11:
870 divided by 91 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 841891.439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
If we divide 510 by 91, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 841891.4395
The remainder is 55 after subtracting 455 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
The number 91 fits into 550 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 841891.43956
Subtracting 546 from 550 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
91 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 841891.43956
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 841891.4395604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
360 divided by 91 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 841891.43956043
Deduct 273 from 360 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 841891.43956043 and a remainder of 8.7e-08.
