91687603 ÷ 355 
We want to figure out the number of times 91687603 can be divided by 355.

Step 1:
355 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 355

On to step 2:
When dividing 91 by 355, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 355

Advancing to step 3:
If we divide 916 by 355, we get 2 and a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 710 from 916, we get 206.
Include the next digit (8) from the dividend after 206, then repeat: 2068 / 355

Advancing to step 4:
When dividing 2068 by 355, we get 5 with a remainder of 293.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1775 from 2068 to get 293.
Take the next digit (7) from the dividend and append it to 293, then repeat: 2937 / 355

On to step 5:
The number 355 fits into 2937 8 times, leaving a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
Deduct 2840 from 2937 and we're left with 97.
Fetch the next digit (6) from the dividend, attach it to 97 and continue: 976 / 355

Step 6:
If we divide 976 by 355, we get 2 and a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 2582.0
If we take 710 away from 976, we end up with 266.
Append the next digit (0) from the dividend to 266 and continue with: 2660 / 355

Advancing to step 7:
If we divide 2660 by 355, we get 7 and a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 25827.0
The remainder is 175 after subtracting 2485 from 2660.
Fetch the next digit (3) from the dividend, attach it to 175 and continue: 1753 / 355

Step 8:
1753 divided by 355 is 4 with a remainder of 333.
The number 4 becomes the next digit in our result. 
Result so far: 258274.0
The remainder is 333 after subtracting 1420 from 1753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 9:
When dividing 3330 by 355, we get 9 with a remainder of 135.
Record the quotient 9 as the next digit in the result. 
Result so far: 258274.9
If we subtract 3195 from 3330, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
When dividing 1350 by 355, we get 3 with a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 258274.93
Deduct 1065 from 1350 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 11:
2850 divided by 355 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 258274.938
Subtract 2840 from 2850 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
When dividing 100 by 355, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 258274.938
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
355 can be fit into 1000 2 times, resulting in a remainder of 290.
The next digit of our result is 2. 
Result so far: 258274.93802
If we take 710 away from 1000, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 14:
2900 divided by 355 is 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 258274.938028
Deduct 2840 from 2900 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.

Advancing to step 15:
If we divide 600 by 355, we get 1 and a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 258274.9380281
If we subtract 355 from 600, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 16:
If we divide 2450 by 355, we get 6 and a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 258274.93802816
The remainder is 320 after subtracting 2130 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 258274.93802816 with a remaining 3.2e-07.
