We look at the division of 91890565 by 742 
Our goal is to divide 91890565 by 742.

Step 1:
If we divide 9 by 742, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 742

On to step 2:
The number 742 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 742

On to step 3:
The number 742 fits into 918 1 times, leaving a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 742 from 918 and we're left with 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 742

Moving on to step 4:
If we divide 1769 by 742, we get 2 and a remainder of 285.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1484 from 1769 to get 285.
Include the next digit (0) from the dividend after 285, then repeat: 2850 / 742

Advancing to step 5:
The number 742 fits into 2850 3 times, leaving a remainder of 624.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we take 2226 away from 2850, we end up with 624.
Grab the next digit (5) from the dividend, add it to 624, then carry on: 6245 / 742

Going ahead to step 6:
742 goes into 6245 8 times with a remainder of 309.
Record the quotient 8 as the next digit in the result. 
Result so far: 1238.0
If we take 5936 away from 6245, we end up with 309.
Append the next digit (6) from the dividend to 309 and continue with: 3096 / 742

Advancing to step 7:
742 goes into 3096 4 times with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 12384.0
If we subtract 2968 from 3096, we get 128.
Bring next digit (5) of the dividend behind the 128 and repeat the process: 1285 / 742

On to step 8:
If we divide 1285 by 742, we get 1 and a remainder of 543.
Use 1 as the next digit of our solution. 
Result so far: 123841.0
Subtracting 742 from 1285 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 9:
When dividing 5430 by 742, we get 7 with a remainder of 236.
The number 7 becomes the next digit in our result. 
Result so far: 123841.7
The remainder is 236 after subtracting 5194 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 10:
2360 divided by 742 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 123841.73
Deduct 2226 from 2360 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 11:
742 can be fit into 1340 1 times, resulting in a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 123841.731
If we subtract 742 from 1340, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 12:
The number 742 fits into 5980 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 123841.7318
If we subtract 5936 from 5980, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
440 divided by 742 is 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 123841.7318
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 14:
742 goes into 4400 5 times with a remainder of 690.
The number 5 becomes the next digit in our result. 
Result so far: 123841.731805
Subtracting 3710 from 4400 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 15:
If we divide 6900 by 742, we get 9 and a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 123841.7318059
If we subtract 6678 from 6900, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 16:
2220 divided by 742 is 2 with a remainder of 736.
Write down 2 as next digit of the result. 
Result so far: 123841.73180592
The remainder is 736 after subtracting 1484 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

After the division, we end up with 123841.73180592 and a remainder of 7.36e-07.
