83410091 ÷ 977 
We want to figure out the number of times 83410091 can be divided by 977.

Going ahead to step 1:
The number 977 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 977

Step 2:
If we divide 83 by 977, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (4) from the dividend, add it to 83, then carry on: 834 / 977

Advancing to step 3:
977 can be fit into 834 0 times, resulting in a remainder of 834.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 834 and we're left with 834.
Append the next digit (1) from the dividend to 834 and continue with: 8341 / 977

On to step 4:
977 can be fit into 8341 8 times, resulting in a remainder of 525.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 525 after subtracting 7816 from 8341.
Append the next digit (0) from the dividend to 525 and continue with: 5250 / 977

Advancing to step 5:
5250 divided by 977 is 5 with a remainder of 365.
The next digit of our result is 5. 
Result so far: 85.0
If we take 4885 away from 5250, we end up with 365.
Take the next digit (0) from the dividend and append it to 365, then repeat: 3650 / 977

Let's proceed to step 6:
The number 977 fits into 3650 3 times, leaving a remainder of 719.
The next digit of our result is 3. 
Result so far: 853.0
If we subtract 2931 from 3650, we get 719.
Fetch the next digit (9) from the dividend, attach it to 719 and continue: 7199 / 977

On to step 7:
7199 divided by 977 is 7 with a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 8537.0
Subtracting 6839 from 7199 leaves us with 360.
Fetch the next digit (1) from the dividend, attach it to 360 and continue: 3601 / 977

Advancing to step 8:
977 goes into 3601 3 times with a remainder of 670.
The number 3 becomes the next digit in our result. 
Result so far: 85373.0
Deduct 2931 from 3601 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 9:
The number 977 fits into 6700 6 times, leaving a remainder of 838.
The next digit of our result is 6. 
Result so far: 85373.6
The remainder is 838 after subtracting 5862 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Advancing to step 10:
When dividing 8380 by 977, we get 8 with a remainder of 564.
The number 8 becomes the next digit in our result. 
Result so far: 85373.68
If we subtract 7816 from 8380, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 11:
The number 977 fits into 5640 5 times, leaving a remainder of 755.
Write down 5 as next digit of the result. 
Result so far: 85373.685
If we subtract 4885 from 5640, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Step 12:
The number 977 fits into 7550 7 times, leaving a remainder of 711.
Use 7 as the next digit of our solution. 
Result so far: 85373.6857
The remainder is 711 after subtracting 6839 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Step 13:
977 goes into 7110 7 times with a remainder of 271.
The next digit of our result is 7. 
Result so far: 85373.68577
If we subtract 6839 from 7110, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

In conclusion, the division gives 85373.68577 with a balance of 0.000271.
